Proton-induced knockout reactions provide a direct means of studying the single particle or cluster structures of target nuclei. In addition, these knockout reactions are expected to play a unique role in investigations of the effects of the nuclear medium on nucleon– nucleon interactions as well as the properties of nucleons and mesons. However, due to the nature of hadron probes, these reactions can suffer significant disturbances from the nuclear surroundings and the quantitative theoretical treatment of such processes can also be challenging. In this article, we review the experimental and theoretical progress in this field, particularly focusing on the use of these reactions as a spectroscopic tool and as a way to examine the medium modification of nucleon–nucleon interactions. With regard to the former aspect, the review presents a semi-quantitative evaluation of these reactions based on existing experimental data. In terms of the latter point, we introduce a significant body of evidence that suggests, although does not conclusively prove, the existence of medium effects. In addition, this paper also provides information and comments on other related subjects.

To search for low-energy resonant structures in isospin T=3/2 three-body systems, we have performed the experiments H3(t,He3)3n and He3(He3,t)3p at intermediate energies. For the 3n experiment, we have newly developed a thick Ti-H3 target that has the largest tritium thickness among targets of this type ever made. The 3n experiment for the first time covered the momentum-transfer region as low as 15 MeV/c, which provides ideal conditions for producing fragile systems. However, in the excitation-energy spectra we obtained, we did not observe any distinct peak structures. This is in sharp contrast to tetraneutron spectra. The distributions of the 3n and 3p spectra are found to be similar, except for the displacement in energy due to Coulomb repulsion. Comparisons with theoretical calculations suggest that three-body correlations exist in the 3n and 3p systems, although not enough to produce a resonant peak.

We present the measured spin correlation coefficient Cy,y for p-3He elastic scattering at 100 MeV at the angles θc.m.=46.9∘–149.2∘ in the center of mass system. The experiment was performed using a 100 MeV polarized proton beam in conjunction with the polarized 3He target. Proton beams were injected to the target, and scattered protons were detected by using E-ΔE detectors which consisted of plastic and NaI(Tl) scintillators. The data are compared with rigorous numerical calculations based on realistic NN potentials as well as with the Δ-isobar excitation. The obtained results indicate that the Cy,y expands the knowledge of the nuclear interactions with Δ-isobar or those including 3NFs that are masked in nucleon-deuteron elastic scattering.

Gamow-Teller (GT) transitions in an exotic neutron-rich nucleus 11Li have been measured via the 11Li(p,n)11Be reaction at 182 MeV/u in inverse kinematics at RI Beam Factory (RIBF) of RIKEN Nishina Center. The neutron detector array PANDORA and the SAMURAI spectrometer were used to detect recoil neutrons and decay products produced in the (p,n) reaction, respectively. Preliminary results of kinematic correlation of recoil neutrons, corresponding to GT transitions, are presented for several decay channels of 11Be reaction product. Fourteen decay channels with light-particle emission from 11Be excited states, including seven new channels, are identified, in addition to the non-particle-emission channel from 11Be ground or low-lying states.

Much research in recent years has focused on circular accelerators that accelerate and store secondary particles with a large momentum spread, such as muons, unstable nuclei, and heavy ions with different charge states. A fixed-field alternating gradient (FFAG) accelerator with large transverse and momentum acceptance has obvious advantages for such requirements. A versatile beam injection method is required to accelerate secondary particles with a large momentum spread and different charge states with an FFAG accelerator. In the present study, a method for charge exchange injection of positive heavy ions using the large momentum acceptance of an FFAG accelerator is proposed. A charge injection system, which converts a He^<1+> beam to a He^<2+> beam, is developed for a 150 MeV FFAG accelerator at the Center for Accelerator and Beam Applied Science (CABAS) of Kyushu University. As the first step to verify the injection method, an orbit shift from one charge state to the other is demonstrated. This is the first demonstration of heavy ion injection using an FFAG accelerator.

We have measured the differential cross section and analyzing power for (p, 2p) reactions that lead to discrete states of residual nuclei at an incident energy of 197 MeV for five kinds of target nuclei, 12C, 16O, 40,48Ca, and 90Zr. The data are compared with distorted-wave impulse approximation calculations using two kinds of global optical potentials. The spectroscopic factors obtained from these calculations agree with those determined in (e, e′p) studies within 20%, except for one orbital of the 90Zr nucleus where the distortion effect is much greater than that for the other orbitals of 90Zr and for other target nuclei. We also observed a clear and visibly distinct j-dependence in the analyzing power.

Publisher：Results in Physics

Background: In our previous paper, we tested the chiral (Kyushu) folding model for 12C+12C scattering, since the profile function in the Glauber mode is constructed for the system. We found that the folding model is reliable for reaction cross sections σR in 30≲Elab≲100MeV and 250≲Elab≲400MeV. Accurate data are available for 12C scattering on 9Be, 12C, 27Al targets in 30≲Elab≲400MeV. Purpose: We determine matter radius rm(exp) of 12C from the accurate σR(exp), using the Kyushu g-matrix folding model. Results: Our result is rm12(exp)=2.352±0.013 fm for 12C. The model is applied for the accurate data on 12C+27 Al scattering, and yields rm(exp)=2.936±0.012 fm for 27Al. Conclusion: Our conclusion is that rm(exp)=2.352±0.013 fm agrees with rm(exp)=2.35±0.02 fm determined from interaction cross sections by Tanihata et al.

Background: The PREX group reported a new skin value, rskin208(PREX2)=0.283±0.071=0.212∼0.354fm. Using the chiral (Kyushu) g-matrix folding model with the proton and neutron densities determined with D1S+GHFB+AMP, we determined neutron skin thickness rskin208(exp)=0.278±0.035 fm from reaction cross sections σR(exp) of p+208Pb scattering, where D1S-GHFB+AMP denotes Gogny-D1S HFB with angular momentum projection (AMP). The method also yielded rskin208(exp)=0.416±0.146 from σR(exp) of 4He+208Pb scattering. In our previous work, we accumulated the 206 EoSs and determined a sloop parameter L=76∼165MeV from the 206 EoSs. The value of L yields rskin208=0.102∼0.354fm. As for 58Ni, a novel method for measuring nuclear reactions in inverse kinematics with stored ion beams was successfully used to extract matter radii rm of 58Ni at the GSI facility. Purpose: As the first aim, we first determine rskin208(exp) from σR(exp) of 3He scattering on 208Pb target and take the weighted mean and its error for rskin208(PREX2), three skin values of p+208Pb, 3,4He+208Pb scattering and rskin208=0.102∼0.354fm based on the 206 EoSs. As the second aim, we determine matter radii rm(exp) of 58,60,64Ni from σR(exp) of 3,4He scattering on 58,60,64Ni targets. Results: Our result is rskin208(exp)=0.512±0.268fm for 3He+208Pb scattering. Our results based on 4He+58,60,64Ni scattering are rm58(exp)=3.734±0.091 fm, rm60(exp)=3.815±0.094 fm, rm64(exp)=4.001±0.093 fm. Our results based on 3He+58,60,64Ni scattering are rm58(exp)=3.709±0.098 fm, rm60(exp)=3.753±0.112 fm, rm64(exp)=3.822±0.142 fm. Conclusion: Our conclusion is rskin208=0.285±0.030fm. It is determined from the 5 skin values mentioned above.

Background: In our previous work, we determined matter radii rm(exp) and neutron-skin thickness rskin(exp) from reaction cross sections σR(exp) of proton scattering on 208Pb, 58Ni, 40,48Ca, 12C targets, using the chiral (Kyushu) g-matrix folding model with the densities calculated with Gogny-D1S-HFB (D1S-GHFB) with angular momentum projection (AMP). The resultant rskin(exp) agree with the PREX2 and CREX values. As for 58Ni, our value is consistent with one determined from the differential cross section for 58Ni＋4He scattering. As for p＋60,62,64N scattering, σR(exp) are available as a function of incident energies Ein, where Ein=22.8∼65.5MeV for 60Ni, Ein=40,60.8MeV for 62Ni, Ein=40,60.8MeV for 64Ni. Purpose: Our aim is to determine matter radii rm(exp) for 60,62,64Ni from the σR(exp). Method: Our method is the Kyushu g-matrix folding model with the densities scaled from D1S-GHFB ＋ AMP densities, Results: Our skin values are rskin(exp)=0.076±0.019,0.106±0.192,0.162±0.176 fm, and rm(exp)=3.759±0.011,3.811±0.107,3.864±0.101 fm for 60,62,64Ni, respectively.

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER

Background: For 4,6,8He, Tanihata et al. determined matter radii rm(σI)=1.57(4),2.48(3),2.52(3) fm from interaction cross sections σI for 4,6,8He scattering on Be, C Al targets at 790 MeV/nucleon. Lu et al. measured the atomic isotope shifts (AIS) for 4,6,8He and determined proton radii rp(AIS) for 4,6,8He. As for p+4,6,8He scattering, reaction cross sections σR(exp) are available at 700 MeV with high accuracy. Aim: Our aim is to determine matter radii rm and skins rskin for 6,8He from the σR(exp) and the rp(AIS). Method: Our model is the Love–Franey t-matrix folding model, since the model is better than the optical limit of Glauber model. Results: Our results for 6,8He are rm(exp)=2.48(3),2.53(2) fm and rskin=0.78(3), 0.82(2) fm. Conclusion: For 6,8He, our results rm(σR) agree with those of Tanihata et al. For 8He, the distance between 4He and the center of mass of valence four neutrons is 2.367 fm.

Lu et al. (2013) determined proton radii rp(AIS) for 4,6,8He with the atomic isotope shifts (AIS). We investigate whether the Love-Franey t-matrix folding model is good for 4,6,8He+12C scattering at 790 MeV per nucleon.

Neutron skin in ⁴⁸Ca determined from p+⁴⁸Ca and ⁴⁸Ca+¹²C scattering

Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER

Background: In our previous paper, we determined rskin208(exp)=0.278±0.035 fm from measured reaction cross sections σR for p+208Pb scattering, using the Kyushu (chiral) g-matrix folding model with the densities calculated with the Gogny-D1S Hartree–Fock–Bogoliubov (D1S-GHFB) with the angular momentum projection (AMP). The value agrees with that of PREX2. Reaction cross sections σR are available for p+48Ca scattering, whereas interaction cross sections σI(≈σR) are available for 48Ca + 12C scattering. As for 48Ca, the high-resolution E1 polarizability experiment (E1pE) yields rskin48(E1pE)=0.14∼0.20fm. Purpose: We determine rskin48(exp) from the data on σR for p+48Ca scattering and from the data on σI for 48Ca+12C scattering. Methods: We use the Kyushu g-matrix folding model with the densities calculated with the D1M-GHFB+AMP densities. The D1M-GHFB+AMP proton and neutron densities are scaled so as to reproduce the data under the condition that the radius rp of the scaled proton density equals the data rp(exp) determined from the electron scattering. We deduce skin values rskin=rn(exp)−rp(exp) from the resulting rn(exp) and the rp(exp) determined from electron scattering. The same procedure is taken for D1S-GHFB+AMP. Results: We regard rskin48(E1pE) as a reference skin value. Using the reference skin value and taking D1M-GHFB+AMP, we determine rskin48(exp)=0.158±0.025 fm for p+48Ca scattering and 0.160±0.058 fm for 48Ca + 12C scattering. Conclusion: We take the weighted mean and its error for the two skin values. The result is rskin48(exp)=0.158±(0.023)exp±(0.012)thfm.

Language：English Publishing type：Research paper (scientific journal)

Background: In the previous paper, we predicted reaction cross sections σR for 40−60,62,64Ca+12C scattering at 280 MeV/nucleon, using the chiral g-matrix folding model with the densities calculated with the Gogny-D1S Hartree–Fock–Bogoliubov (GHFB) with and without the angular momentum projection (AMP), since Tanaka et al. measured interaction cross sections σI(≈σR) for 42−51Ca in RIKEN and determined neutron skin rskin(RIKEN) using the optical limit of the Glauber model with the Woods–Saxon densities. Purpose: Our purpose is to reanalyze the rskin from the σI using the chiral g-matrix folding model. Our analysis is superior to theirs, since the chiral g-matrix folding model (the GHFB and GHFB+AMP densities) is much better than the optical limit of the Glauber model (the Woods–Saxon densities). Methods: Our model is the chiral g-matrix folding model with the densities scaled from the GHFB and GHFB+AMP densities. Results: We scale the GHFB and GHFB+AMP densities so that the σR of the scaled densities can agree with the central values of σI under the condition that the proton radius of the scaled proton density equals the data determined from the isotope shift based on the electron scattering. The rskin thus determined are close to their results rskin42−51(RIKEN), except for 48Ca. For 48Ca, our value rskin48 is 0.105 ± 0.06 fm, while their value is rm48(RIKEN)=0.146±0.06 fm. We then take the weighted mean and its error of our result rskin48(σI)=0.105±0.06 fm and the result rskin48(E1pE)=0.17±0.03 fm of the high-resolution E1 polarizability experiment (E1pE). Our final result is rskin48=0.157±0.027 fm. Conclusion: Our conclusion is rskin48=0.157±0.027 fm for 48Ca. For 42−47,49−51Ca, our results on rskin are similar to theirs. Our result for 48Ca is related to CREX.

In order to study three-nucleon force (3NF) effects in three-nucleon scattering we performed the measurements of the cross sections and the spin observables for the deuteron–proton (dp) scattering with the polarized deuteron beams at the incident energies up to 135 MeV/nucleon. Recently we have extended the measurements at the RIKEN RI Beam Factory (RIBF) with the polarized deuteron beams at 190, 250, and 300 MeV/nucleon.

Extraction of the Landau-Migdal Parameter from the Gamow-Teller Giant Resonance in Sn-132
The key parameter to discuss the possibility of the pion condensation in nuclear matter, i.e., the so-called Landau-Migdal parameter g', was extracted by measuring the double-differential cross sections for the (p, n) reaction at 216 MeV/u on a neutron-rich doubly magic unstable nucleus, Sn-132 with the quality comparable to data taken with stable nuclei. The extracted strengths for Gamow-Teller (GT) transitions from Sn-132 leading to Sb-132 exhibit the GT giant resonance (GTR) at the excitation energy of 16.3 +/- 0.4(stat) +/- 0.4(syst) MeV with the width of Gamma = 4.7 +/- 0.8 MeV. The integrated GT strength up to Ex = 25 MeV is S-GT(-) = 53 +/- 5(stat)(-10)(+11)(syst), corresponding to 56% of Ikeda's sum rule of 3(N - Z) = 96. The present result accurately constrains the Landau-Migdal parameter as g' = 0.68 +/- 0.07, thanks to the high sensitivity of the GTR energy to g'. In combination with previous studies on the GTR for Zr-90 and Pb-208, the result of this work shows the constancy of this parameter in the nuclear chart region with (N - Z)/A = 0.11 to 0.24 and A = 90 to 208.

The S30(α,p)Cl33 reaction has been identified in several type-1 x-ray burst (XRB) sensitivity studies as a significant reaction within the αp process, possibly influencing not only the abundances of burst ashes but also the bolometric shape of double-peaked light curves coming from certain XRB systems. Given the dearth of experimental data on the S30(α,p) Cl33 reaction at burst temperatures, we have performed high energy-resolution forward-angle Ar36(p,t)Ar34 measurements in order to identify levels in Ar34 that could appear as resonances in the S30(α,p)Cl33 reaction. Energies of levels identified in this work, along with model-based assumptions for spin assignments and spectroscopic factors, were then used to determine a rate for the S30(α,p)Cl33 reaction based on a narrow-resonance formalism. The rates determined in this work are then compared with two standard Hauser-Feshbach model predictions over a range of XRB temperatures.

We report measurements of cross sections and analyzing powers for nucleon-knockout (p⃗,np) reactions of 2H, 6Li, and 12C at 296 MeV using the RCNP NPOL3 neutron detector and large acceptance spectrometer. The 1s and 1p knockout reactions were successfully separated with a separation-energy resolution of approximately 6 MeV. The resulting data were compared with plane-wave and distorted-wave impulse approximation calculations employing the nucleon-nucleon t matrix in free space. No significant differences were identified in the case of the present analyzing power data, in contrast to the significant reductions observed in (p⃗,2p) values. The conventional Pauli blocking and nuclear binding effects with the g matrix and the relativistic effect of nucleon mass reduction in the nuclei are also discussed.

Language：English

The goal of this study is to determine the spin-orbit splitting of 1p proton orbits in oxygen isotopes. An experiment for the exclusive measurement of the (⃗p, 2p) reaction was carried out at the SHARAQ beamline at RI Beam Factory, RIKEN. Beam containing oxygen unstable isotopes with the kinetic energy of around 250 MeV bombarded a polarized solid proton target. Proton separation energy was calculated from the momentum vectors of two scattered protons. For 14O(⃗p, 2p), the transition strengths of the 14O(⃗p, 2p)13N reaction leading to the ground state and excited states were separated by the particle identification of the residual nucleus. As a result, 6.3 MeV of 1p spin-orbit splitting of 14O was obtained.

Search for a permanent EDM using laser cooled radioactive atom
The search for the electric-dipole moment (EDM) of laser-cooled francium (Fr) atoms could lead to a measurement for the electron EDM. It is predicted that the electron EDM would be enhanced by approximately three orders of magnitude in heavy atoms such as Fr. Laser-cooling and trapping techniques are expected to suppress statistical and systematic errors in precision measurements. The magneto-optical trap was achieved using stable rubidium in a developing factory of laser-cooled radioactive atoms. In light of the results from the rubidium experiments, we found that an upgrade of each apparatus is preferred for Fr trapping. © Owned by the authors, published by EDP Sciences, 2014.

Development of the measurement system for the search of an electric dipole moment of the electron with laser-cooled francium atoms
We plan to measure the permanent electric dipole moment (EDM) of the electron, which has the sensitivity to the CP violation in theories beyond the standard model by using the laser-cooled francium (Fr) atom. This paper reports the present status of the EDM measurement system. A high voltage application system was constructed in order to produce the strong electric field (100 kV/cm) needed for the experiment. After conditioning, the leakage current was 10 pA when a high voltage of 43 kV was applied. Also, a drift of an environmental field was measured at the planned location of the Fr-EDM experiment. The drift is suppressed at present down to the level of 10 pT by installing a 4-layermagnetic shield. Improvements are still needed to reach the required field stability of 1 fT. © Owned by the authors, published by EDP Sciences, 2014.

Development of francium atomic beam for the search of the electron electric dipole moment
For the measurement of the electron electric dipole moment using Fr atoms, a Fr ion-atom conversion is one of the most critical process. An ion-atom converter based on the "orthotropic" type of Fr source has been developed. This converter is able to convert a few keV Fr ion beam to a thermal atomic beam using a cycle of the surface ionization and neutralization. In this article, the development of the converter is reported. © Owned by the authors, published by EDP Sciences, 2014.

We have measured all deuteron analyzing powers A_y^d, A_yy, A_xx, A_xz for deuteron-proton elastic scattering at 294 MeV/nucleon in order to study the properties of three nucleon forces (3 NFs). Measurement was made at in an angular range of θ_c.m. = 35.6°-163.0°. Obtained data were compared with Faddeev calculations with and without the 3 NFs. At θ_c.m. ≲ 120° all the data have general agreement with the calculations, while the measured data at θ_c.m. ≳ 120° are not explained by any theoretical calculations. These results were consistent with those at 250 MeV/nucleon.

Extraction of anti-analog giant dipole resonance and neutron skin thickness for Pb-208
The anti-analog giant dipole resonance (AGDR) was separated from other excitations such as the spin-dipole resonance by multipole decomposition analysis of the Pb-208((p) over right arrow, (n) over right arrow) reaction at a bombarding energy of T-p = 296 MeV. The polarization transfer observables were found to be useful for carrying out this separation. The energy difference between the AGDR and the isobaric analog state (IAS) was determined to be Delta E = 8.69 +/- 0.36 MeV, where the uncertainty includes both statistical and systematic contributions. Theoretical calculations using the proton-neutron relativistic quasi-particle random phase approximation predicted a strong correlation between Delta E and the neutron skin thickness Delta R-pn. Under the assumption that the correlation predicted in this model is correct, the present Delta E value corresponds to a neutron skin thickness of Delta R-pn = 0.216 +/- 0.046 +/- 0.015 fm, where the first and second uncertainties are the experimental and theoretical uncertainties, respectively.

A multipole decomposition technique was applied to the spectra to extract the Gamow-Teller (GT) component. The integrated GT strengths up to an excitation energy of 30 MeV in the intermediate nucleus 116In are 40 ± 6 and 11 ± 1 in the (p,n) and (n,p) spectra, respectively, including the component from the isovector spin monopole (IVSM). The spectra are compared with those obtained from a theoretical calculation with a quasiparticle random phase approximation, where the contribution from the IVSM component as well as the interference effect between the GT and IVSM components are fully taken into account.

The rise time of stellar x-ray bursts is a signature of thermonuclear runaway processes in the atmosphere of neutron stars and is highly sensitive to a series of (α,p) reactions via high-lying resonances in sd-shell nuclei. Lacking data for the relevant resonance levels, the stellar reaction rates have been calculated using statistical, Hauser-Feshbach models, assuming a high-level density. This assumption may not be correct in view of the selectivity of the (α,p) reaction to natural parity states. We measured the 28Si(p,t)26Si reaction with a high-resolution spectrometer to identify resonance levels in 26Si above the α-emission threshold at 9.164 MeV excitation energy. These resonance levels are used to calculate the stellar reaction rate of the 22Mg(α,p)25Al reaction and to test the validity of the statistical assumption.

Since the identification of ongoing Al26 production in the universe, the reaction sequence Mg24(p,γ)Al25(β⁺ν)Mg25(p,γ)Al26 has been studied intensively. At temperatures where the radiative capture on Al25 (t1/2=7.2 s) becomes faster than the β⁺ decay, the production of Al26 can be reduced due to the depletion of Al25. To determine the resonances relevant for the Al25(p,γ)Si26 bypass reaction, we measured the Si28(p,t)Si26 reaction with high-energy precision using the Grand Raiden spectrometer at the Research Center for Nuclear Physics, Osaka. Several new energy levels were found above the p threshold and for known states excitation energies were determined with smaller uncertainties. The calculated stellar rates of the bypass reaction agree well with previous results, suggesting that these rates are well established.

Under the assumption of good isospin symmetry, T_z = ±3/2 → ±1/2 Gamow-Teller (GT) transitions in a mass A isobar are analogous, where T_z is the z component of isospin T defined by 1/2(N - Z). We studied the T_z = +3/2 → +1/2 GT transitions by using the ³⁷Cl(³He,t)³⁷Ar and ⁴¹K( ³He,t)⁴¹Ca reactions at E_beam = 140 MeV/nucleon. The GT transition strengths in ³⁷Ar and ⁴¹Ca were obtained up to the excitation energy (E_x) of 14.2 MeV and 10.4 MeV with energy resolutions of 30 and 35 keV, respectively. The obtained GT strengths were compared with those of the T_z = -2/3 → -1/2 mirror transitions, measured by the β-decay of ³⁷Ca and ⁴¹Ti, respectively. It was found that the overall distributions of the mirror transitions were similar in both A = 37 and A = 41 systems. In A = 37 the differences seen at lower excitation energies are suggested to be the effect of the tensor interaction in the charge-exchange reaction. The differences seen at higher excitation energies are suggested to be the effect of the Coulomb interaction that can break the mirror symmetry of the strength distributions.

Language：English Publishing type：Research paper (scientific journal)

The cross sections and analyzing powers for the Ca40(p□,2p) reaction were measured. The strength distributions for the deep-hole states were obtained by a multipole decomposition analysis. The centroid energies and widths of the hole-state strengths of the 1p and 1s1/2 orbitals in Ca40 were determined. The spectroscopic factors for the deeply bound 1p and 1s1/2 orbitals were extracted as 49±10% and 78±14% of the sum-rule limits of the independent-particle shell model, respectively. A strong influence of the nucleon-nucleon correlations on the spectroscopic factors is suggested.

The double differential cross sections for the ¹¹⁶Cd(p,n) and ¹¹⁶Sn(n,p) reactions at 300 MeV have been measured over a wide excitation-energy region including Gamow-Teller (GT) giant resonance (GTGR) for studying GT transition strengths in the intermediate nucleus of the ¹¹⁶Cd double-β decay, namely ¹¹⁶In. A large amount of the strengths in the β⁺ direction has been newly found in the energy region up to 30 MeV, which may imply that the GT strengths in the GTGR region contribute to the nuclear matrix element of the two-neutrino double-β decay.

x-ray bursts are identified as thermonuclear explosions in the outer atmosphere of accreting neutron stars. The thermonuclear runaway is fueled by the αp process that describes a sequence of (α,p) reactions triggered by the Ne18(α,p)Na21 breakout reaction from the hot CNO cycles. We studied the level structure of the compound nucleus Mg22 by measuring the Mg24(p,t)Mg22 reaction at the Grand Raiden spectrometer at Research Center for Nuclear Physics, Osaka. A large number of α-unbound states was identified and precise excitation energies were determined. Based on shell model and α-cluster model calculations we predict the level parameters for determining the stellar reaction rate of Ne18(α,p)Na21 for a wide temperature range. x-ray burst simulations have been performed to study the impact of the reaction on the x-ray burst luminosity.

We present measurements of the cross section and a complete set of polarization observables for the Gamow-Teller¹²C(p→, n→)¹²N(g.s.; 1⁺) reaction at an incident proton energy of 296 MeV. The complete set of polarization observables is used to separate the cross section into spin-longitudinal and spin-transverse components. From the comparison with the distorted wave impulse approximation calculations employing random phase approximation response functions, we found that our data showed the existence of the pionic and rho-mesonic correlations in nuclei.

Differential cross sections and complete sets of polarization observables are presented for the Gamow-Teller C12(p→,n→)N12(g.s.,1+) reaction at a bombarding energy of 296 MeV with momentum transfers q of 0.1 to 2.2 fm-1. The polarization transfer observables are used to deduce the spin-longitudinal cross section, IDq, and spin-transverse cross sections, IDp and IDn. The data are compared with calculations based on the distorted-wave impulse approximation (DWIA) using shell-model wave functions. Significant differences between the experimental and theoretical results are observed for all three spin-dependent IDi at momentum transfers of q O. 5 -1, suggesting the existence of nuclear correlations beyond the shell model. We also performed DWIA calculations employing random-phase approximation (RPA) response functions and found that the observed discrepancy is partly resolved by the pionic and -mesonic correlation effects.

²²Mg, ³⁰S, ³⁴Ar and ³⁸Ca have been investigated using (p,t) reactions at RCNP with the intent of identifying energy levels in nuclei that determine the reaction rates along the pathway of the αp-process. These experiments exploit the high resolution and 0° capabilities of the Grand Raiden spectrometer and the WS beamline, which can deliver a fully dispersion matched beam to target. The level information is vital to understanding the nucleosynthesis occurring during explosive hydrogen burning, which, for example, is thought to occur during type I X-ray bursts. In the case of ²²Mg, new reaction rate calculations have been performed for the ¹⁸Ne(α,p)²¹Na reaction. The experimental technique will be discussed, and the experimental results will be presented.

High resolution study of isovector negative parity states in the O16(He3,t)F16 reaction at 140 MeV/nucleon
The isovector transitions from the ground state (g.s.) of O16 to the negative parity states in F16, i.e., the Jπ=0- g.s., the 0.193 MeV, 1- state, the 0.424 MeV, 2- state, the 0.721 MeV, 3- state, and the 4- "stretched" state at 6.372 MeV, were studied by using a high resolution O16(He3,t)F16 reaction at 140 MeV/nucleon. With the help of high energy resolution, these states were, for the first time, clearly resolved in a charge exchange reaction at an intermediate energy, which favorably excites spin-flip states. Angular distributions of the reaction cross sections were measured in the laboratory frame from 0° to 14°. Parameters of phenomenological effective interactions were derived so as to reproduce these angular distributions in distorted wave Born approximation (DWBA) calculations. The angular distribution of the 0- state could be reproduced well at θc.m.<10°. The empirical values, however, are larger by a factor of 2-2.5 in the larger angle region, where the contribution of the so-called "condensed pion field" is expected. The high resolution also enabled the decay widths of these states to be measured. © 2009 The American Physical Society.

Gamow-Teller unit cross sections of the (p,n) reaction at 198 and 297 MeV on medium-heavy nuclei
Gamow-Teller (GT) unit cross sections, sigma(GT), are obtained at 198 and 297 MeV by measuring the double differential cross sections at 0(degrees) for the (p,n) reaction on Ni-58, Zn-70, Cd-114, Sn-118, and Sn-120. The mass dependence of sigma(GT) and the ratio of sigma(GT) to the Fermi unit cross section, sigma(F), (R-2) are also derived in the mass region of 58 <= A <= 120. The sigma(GT) value for Zr-90 at 297 MeV interpolated using the A-dependence obtained herein agrees with that used in a previous analysis where the GT transition strength over a wide energy region up to the continuum was discussed. However, the deduced Ni-64 sigma(GT) value at 198 MeV is 20% smaller than that obtained from the analysis of a previous (n,p) measurement. The present R-2 values in the mass region heavier than Ca-42 are larger than those in the region up to Ca-42 and increase as a function of A.

Language：English Publishing type：Research paper (other academic)

Recently it was found that, the differential cross sections of elastic Nd scattering below 150 MeV can be well reproduced by incorporating a 3NF in Faddeev calculations based on modern nucleon-nucleon (NN) interactions. On the other hand, the differential cross sections for nd and pd at 250 MeV show large discrepancies between the data and the Faddeev calculations with a 3NF. This indicates the existence of the missing features of the three nucleon force in this energy region. For the next step in the 3NF study, we have measured the vector analyzing power A_y and the differential cross sections for the ²H(p̄, pp)n breakup reaction at 250 MeV. The experiment, was carried out by detecting two protons in the final state with using the double-armed spectrometer Grand Raiden (GR) and the Large Acceptance Spectrometer (LAS) at the Research Center for Nuclear Physics (RCNP). The data was compared with the results of Faddeev calculations with and without a 3NF.

Language：English Publishing type：Research paper (scientific journal)

A complete set of polarization transfer observables has been measured for the ¹²C(p, n) reaction at T_p = 296MeV and θ_lab = 0°. The measured polarization transfer observables indicate that the spin-dipole resonance at E_x ≃ 7MeV has greater 2^- strength than 1^- strength, which is consistent with recent experimental and theoretical studies. The total spin transfer Σ(0°) deduced from the polarization transfer observables indicates a predominance of the spin-flip strength in the continuum. The exchange tensor interaction at a large momentum transfer of Q ≃ 3:6 fm^-1 is discussed.

We report measurements of the cross section and a complete set of polarization observables for the Gamow-Teller ¹²C (over(p, →), over(n, →)) ¹²N (g.s., 1⁺) reaction at a bombarding energy of 296 MeV. The data are compared with distorted wave impulse approximation calculations employing transition form factors normalized to reproduce the observed beta-decay ft value. The cross section is significantly under-predicted by the calculations at momentum transfers q ≳ 0.5 fm^-1. The discrepancy is partly resolved by considering the non-locality of the nuclear mean field. However, the calculations still under-predict the cross section at large momentum transfers of q ≃ 1.6 fm^-1. We also performed calculations employing random phase approximation response functions and found that the observed enhancement can be attributed in part to pionic correlations in nuclei.

Spin correlation parameter Cyy of p+He3 elastic backward scattering
We measured the differential cross section and the spin correlation parameter Cyy of the p→+3He→ elastic backward scattering at 200, 300, and 400 MeV at θ=180° in the center-of-mass frame to study the mechanism of the reaction and to examine the validity of the He3 wave functions based on two different realistic two-body forces. This is the first measurement of the spin correlation parameter Cyy of the p→+3He→ EBS at intermediate energies. The experimental results were compared with few-body calculations, including three reaction mechanisms: two-nucleon-pair exchange, pion exchange, and direct pp scattering. It was found that few-body calculations describe the differential cross-section data reasonably well. The spin correlation parameter Cyy shows clear evidence for the two-nucleon-pair exchange processes in the reaction, demonstrating that the spin observables are helpful for deeper understanding of the reaction mechanism. © 2007 The American Physical Society.

Inelastic α scattering on ¹⁶O is studied at 400 MeV using an ice target. Near the 4α breakup threshold of 14.4 MeV, a broad peak is observed at an excitation energy of 13.6 ± 0.1 MeV with a width of 0.6 ± 0.2 MeV. The spin-parity is estimated to be 0⁺ from the momentum-transfer dependence. The observed width is significantly larger than that of the 0⁺ state at 12.0 MeV with the α + ¹²C structure, indicating a well-developed α cluster structure. The magnitude of the cross section is sensitive to the density distribution of the constituent α clusters. The observed cross section is consistent with the theoretical prediction for the α cluster condensed state, characterized by its dilute density distribution with a large root-mean-square radius.

The differential cross sections and vector analyzing powers for nd elastic scattering at En=248 MeV were measured for 10°-180° in the center-of-mass (c.m.) system. To cover the wide angular range, the experiments were performed separately by using two different setups for forward and backward angles. The data are compared with theoretical results based on Faddeev calculations with realistic nucleon-nucleon (NN) forces such as AV18, CD Bonn, and Nijmegen I and II, and their combinations with the three-nucleon forces (3NFs), such as Tucson-Melbourne 99 (TM99), Urbana IX, and the coupled-channel potential with Δ-isobar excitation. Large discrepancies are found between the experimental cross sections and theory with only 2N forces for θc.m.>90°. The inclusion of 3NFs brings the theoretical cross sections closer to the data but only partially explains this discrepancy. For the analyzing power, no significant improvement is found when 3NFs are included. Relativistic corrections are shown to be small for both the cross sections and the analyzing powers at this energy. For the cross sections, these effects are mostly seen in the very backward angles. Compared with the pd cross section data, quite significant differences are observed at all scattering angles that cannot be explained only by the Coulomb interaction, which is usually significant at small angles.

The differential cross sections and vector analyzing powers for nd elastic scattering at En=248 MeV were measured for 10°-180° in the center-of-mass (c.m.) system. To cover the wide angular range, the experiments were performed separately by using two different setups for forward and backward angles. The data are compared with theoretical results based on Faddeev calculations with realistic nucleon-nucleon (NN) forces such as AV18, CD Bonn, and Nijmegen I and II, and their combinations with the three-nucleon forces (3NFs), such as Tucson-Melbourne 99 (TM99), Urbana IX, and the coupled-channel potential with Δ-isobar excitation. Large discrepancies are found between the experimental cross sections and theory with only 2N forces for θc.m.>90°. The inclusion of 3NFs brings the theoretical cross sections closer to the data but only partially explains this discrepancy. For the analyzing power, no significant improvement is found when 3NFs are included. Relativistic corrections are shown to be small for both the cross sections and the analyzing powers at this energy. For the cross sections, these effects are mostly seen in the very backward angles. Compared with the pd cross section data, quite significant differences are observed at all scattering angles that cannot be explained only by the Coulomb interaction, which is usually significant at small angles. © 2007 The American Physical Society.

The differential cross sections and the vector analyzing powers for the nd elastic scattering at E_n = 250 MeV have been measured for the study of the three-nucleon force (3NF) effects in the Coulomb-free system. To cover a wide angular region, the experiments were performed by using two different methods at the (n, p) facility and at the NTOF facility which constructed at the Research Center for Nuclear Physics (RCNP). The results were compared with theoretical predictions of the Faddeev calculations based on the modern nucleon-nucleon (NN) forces with the three-nucleon force (3NF). The inclusion of 3NFs leads to a good description of the cross section except for the backward angles. The results were also compared with the theoretical predictions with relativistic corrections. The direct data-to-data comparison of the cross sections of the nd and pd was performed.

Language：English Publishing type：Research paper (scientific journal)

We report measurements of the cross section and a complete set of polarization observables for the ²⁸Si (over(p, →), over(n, →)) ²⁸P (6^-) reaction at a bombarding energy of 198 MeV. The data are compared with distorted wave impulse approximation calculations employing response functions normalized to inelastic electron scattering. The spin-longitudinal polarized cross section I D_q is slightly over-predicted by the calculations, while the normal spin-transverse polarized cross section I D_n is significantly under-predicted. The calculated in-plane spin-transverse I D_p and spin-scalar I D₀ polarized cross sections agree well with the experimental data. These results are consistent with those for ²⁸Si (over(p, →), over(p, →)^′) ²⁸Si (6^-, T = 1) scattering at the same energy, and thus it is concluded that isospin-mixing effects are not responsible for the discrepancy between theory and experiment in the (over(p, →), over(p, →)^′) case. Energy half-off-shell effects as medium effects on the effective nucleon-nucleon interaction are also investigated and found to be too small to be responsible for the discrepancy.

The cross section of the O16(p,p′)O16(0-,T=1) scattering was measured at a bombarding energy of 295 MeV in the momentum transfer range of 1.0fm-1≤qc.m.≤2.1fm-1. The isovector 0- state at Ex=12.8MeV is clearly separated from its neighboring states owing to the high energy resolution of about 30 keV. The cross section data were compared with distorted wave impulse approximation (DWIA) calculations employing shell-model wave functions. The observed cross sections around qc.m.≃1.7fm-1 are significantly larger than obtained by these calculations, suggesting pionic enhancement as a precursor of pion condensation in nuclei. The data are well reproduced by DWIA calculations using random phase approximation response functions including the Δ isobar that predict pionic enhancement.

Under the assumption that isospin I is a good quantum number, isobaric analog states and various analogous transitions are expected in isobars with mass number A. The strengths of T_z=+3/2→+1/2 analogous Gamow-Teller (GT) transitions and analogous M1 transitions within the A=41 isobar quartet are compared in detail. The T_z= +3/2+1/2 GT transitions from the J^π=3/2⁺ ground state of ⁴¹K leading to excited J^π = 1/2⁺, 3/2 ⁺, and 5/2⁺ states in ⁴¹Ca were measured using the (³He,t) charge-exchange reaction. With a high energy resolution of 35 keV, many fragmented states were observed, and the GT strength distribution was determined up to 10 MeV excitation energy (E_x). The main part of the strength was concentrated in the E_x =4-6 MeV region. A shell-model calculation could reproduce the concentration, but not so well details of the strength distribution. The obtained distribution was further compared with two results of ⁴¹Ti βdecay studying the analogous T^z=-3/2→-1/2 GT strengths. They reported contradicting distributions. One-to-one correspondences of analogous transitions and analog states were assigned up to E_x=6 MeV in the comparison with one of these ⁴¹Ti β-decay results. Combining the spectroscopic information of the analog states in ⁴¹Ca and ⁴¹ Sc, the most probable J^π values were deduced for each pair of analog states. It was found that 5/2⁺ states carry the main part of the observed GT strength, while much less GT strength was carried by 1/2⁺ and 3/2⁺ states. The gross features of the GT strength distributions for each J were similar for the isospin analogous T_z=±3/ 2→±1/2 transitions, but the details were somewhat different. From the difference of the distributions, isospin-asymmetry matrix elements of ≈8 keV were deduced. The Coulomb displacement energy, which is sensitive to the configuration of states, showed a sudden increase of about 50 keV at the excitation energy of 3.8 MeV. The strengths of several Ml transitions to the IAS in ⁴¹Ca were compared with the strengths of analogous GT transitions. It was found that ratios of the M1 and GT transition strengths were similar, suggesting that the contributions of the lτ term in M1 transitions are small.

Language：English Publishing type：Research paper (scientific journal)

Differential cross sections and a complete set of polarization observables have been measured in the quasielastic ²H(p,n) reaction at a bombarding energy of 345 MeV and laboratory scattering angles of 16°, 22°, and 27°. The data are compared with plane-wave impulse approximation calculations employing an optimal factorization approximation. The agreement between the experimental and theoretical results validates these approximations in the present momentum- and energy-transfer regions. The experimental spin-longitudinal and spin-transverse response functions, R _L and R_T, respectively, are deduced from the data. The obtained R_T is consistent with that obtained from the quasielastic electron scattering. The theoretical calculations with the Reid soft core potential give good descriptions for R_L and R_T, whereas the latter is slightly underestimated around the quasielastic peak.

Versatile production method of thin targets supported by PVA
Thin self-supporting targets are indispensable in high energy-resolution studies using a magnetic spectrometer. However, nuclear targets of alkaline and alkaline-earth metal or halogen isotopes are not easily available. In order to produce thin target foils of these elements for the use in charge-exchange reactions, we take advantage of the fact that the stable isotopes of these elements have relatively small negative Q values, while12C and16O have large negative Q values. Therefore, even if organic compounds containing carbon and oxygen are used as supporting material, clean spectra on alkaline and alkaline-earth metal or halogen targets can be obtained up to the excitation energies of Q-value differences. A technique to produce thin foils of the chemical compounds Na2CO3,K2CO3,CaCO3and CaCl2was developed using polyvinylalcohol as supporting material. Foils with a total thickness of 1-2 mg/cm2were produced and used as targets in a (3He,t) reaction study at an incident energy of 420 MeV. Owing to the small contributions of energy-loss differences of beam and reaction products in such thin targets, a very good resolution of ΔE/E=7×10-5was achieved in combination with a high-resolution magnetic spectrometer. © 2003 Elsevier B.V.

The deuteron-to-proton polarization-transfer coefficients for d-p elastic scattering were precisely measured with an incoming deuteron energy of 135 MeV/nucleon at the RIKEN Accelerator Research Facility. The data are compared to theoretical predictions based on exact solutions of the three-nucleon Faddeev equations with high-precision nucleon-nucleon forces combined with the current, most popular three-nucleon force (3NF) models: the 2π-exchange Tucson-Melbourne model, a modification thereof based on chiral symmetry, TM'(99), and the Urbana IX 3NF. Theory predicts large 3NF effects, especially in the angular range around the cross section minimum, predominantly for K

Language：English Publishing type：Research paper (scientific journal)

Differential cross sections and a complete set of polarization observables have been measured for quasielastic (p^→,n^→) reactions on ¹²C and ⁴⁰Ca at a bombarding energy of 345 MeV. The laboratory momentum transfers are q_lab ≃ 1.2, 1.7, and 2.0 fm^-1 for ¹²C and q_lab≃ 1.7 fm ^-1 for ⁴⁰Ca. In these momentum transfer regions, the isovector spin-longitudinal interaction is attractive where the one-pion exchange is dominant. The spin-longitudinal and spin-transverse polarized cross sections, ID_q and ID_p, are deduced. The theoretically expected enhancement in the spin-longitudinal mode is observed at q _lab≃1.7 and 2.0 fm^-1. The observed ID_q is consistent with the pionic enhanced ID_q evaluated in distorted wave impulse approximation (DWIA) calculations employing random phase approximation (RPA) response functions. The enhanced ID_q implies the existence of a precursor to pion condensation in nuclei. On the other hand, the theoretically predicted quenching in the spin-transverse mode is not observed. The observed ID_p is not quenched, but rather enhanced relative to that predicted via the DWIA+RPA calculations. Two-step contributions are responsible in part for the enhancement of ID_p.

Calibration of the effective analyzing power for a ³He polarimeter at 443 MeV
The effective analyzing power for a 3He polarimeter was calibrated at E3He = 443 MeV. For the calibration, the absolute magnitude of the polarization was determined by means of the double scattering method using the 3He scattering on 12C at 7° in the laboratory frame. The effective analyzing power of Ayeff = 0.232±0.010-0.015+0.017 was obtained for the polarimeter with a plastic scintillator of 16 mm thickness as analyzer. The energy dependence of Ayeff was measured. The first data of the induced polarization for 3He+12C elastic scattering at E3He = 443 MeV will be presented. © 2003 Elsevier Science B.V.

Cross section and induced polarization in 3He elastic scattering at 413 MeV
Angular distributions of the differential cross section and the induced polarization of He-3 elastic scattering on C-12, Ni-58, and Zr-90 targets were measured at 443 MeV incident energy. This is the first measurement of 3He spin observables at intermediate energies. Cross sections and polarizations were measured in the range of center-of-mass angles of 5degrees- 30degrees and 5degrees- 20degrees, respectively. The polarization was measured with the focal plane polarimeter system of the Grand Raiden spectrometer, which was calibrated for He-3 at the present energy. The optical potential parameters including the spin-orbit term were determined by a systematic search procedure. The diffuseness parameter of the spin-orbit potential was about 0.6 - 0.8 fm in contrast to much smaller values of 0.2 - 0.3 fm reported at lower energies. The energy dependence of the reduced volume integrals of the optical potential was found to be similar to that observed for protons at intermediate energies, but the real potential terms were smaller. Single folding (SF) model calculations were performed and compared with the experimental data. We found that the renormalization factors used to modify the SF potential were necessary in order to obtain a good fit to the data. These results call for an appropriate density dependent nucleon-nucleus interaction in the He-3 nucleus.

We have measured the cross sections and analyzing powers Ay and Ayy for the elastic and inelastic scattering of deuterons from the 0⁺(g.s.), 2⁺(4.44 MeV), 3^-(9.64 MeV), 1⁺(12.71 MeV), and 2^-(18.3 MeV) states in ¹²C at an incident energy of 270 MeV. The data are compared with microscopic distorted-wave impulse approximation calculations where the projectile-nucleon effective interaction is taken from the three-nucleon t-matrix given by rigorous Faddeev calculations presently available at intermediate energies. The agreement between theory and data compares well with that for the (p, p′) reactions at comparable incident energies/nucleon.

Language：English

Cross Sections and polarization transfer observables in the ¹⁶O(p,p′) reactions at 392 MeV were measured at several angles between θ_lab =0° and 14°. The non-spin-flip (ΔS = 0) and spin-flip (ΔS = 1) strengths in transitions to several discrete States and broad resonances in ¹⁶O were extracted using a model-independent method. The giant resonances in the energy region of E_x = 19-27 MeV were found to be predominantly excited by ΔL = 1 transitions. The strength distribution of spin-dipole transitions with ΔS = 1 and ΔL = 1 were deduced. The obtained distribution was compared with a recent shell model calculation. Experimental results are reasonably explained by distorted-wave impulse-approximation calculations with the shell model wave functions.

The analyzing powers of π+ and π- were measured using an incident 22-GeV/c transversely polarized proton beam at the Brookhaven Alternating Gradient Synchrotron. A magnetic spectrometer measured π± inclusive asymmetries on a hydrogen and a carbon target. An elastic polarimeter with a CH2 target measured pp elastic-scattering asymmetries to determine the beam polarization using published data for the pp elastic analyzing power. Using the beam polarization determined from the elastic polarimeter and asymmetries from the inclusive spectrometer, analyzing powers AN for π± were determined in the xF and PT ranges (0.45-0.8) and (0.3-1.2 GeV/c), respectively. The analyzing power results are similar in both sign and character to other measurements at 200 and 11.7 GeV/c, confirming the expectation that high-energy pion inclusive analyzing powers remain large and relatively energy independent. This suggests that pion inclusive polarimetry may be a suitable method for measuring future beam polarizations at BNL RHIC or DESY HERA. Analyzing powers of π+ and π- produced on hydrogen and carbon targets are the same. Various models to explain inclusive analyzing powers are also discussed.

High resolution beam line for the Grand Raiden spectrometer
We have designed and constructed a new beam line which can accomplish both lateral and angular dispersion matching with the Grand Raiden spectrometer. In dispersive mode, lateral and angular dispersions of the beam line are b16= 37.1 m and b26= -20.0 rad, respectively, to satisfy matching conditions for Grand Raiden. In achromatic mode, the beam line satisfies the double achromatic condition of b16= b26= 0. The magnifications of the beam line are (Mx, My) = (-0.98, 0.89) and (-1.00, -0.99) for dispersive and achromatic modes, respectively. In the commissioning experiments, we have succeeded to separate the first excited 2+state of168Er with Ex= 79.8 keV clearly from the ground state in the (p, p′) reaction. We achieved energy resolutions of ΔE = 13.0 ± 0.3 and 16.7 ± 0.3 keV in full width at half-maximum for 295 and 392 MeV protons, respectively. These energy resolutions agree with the resolving power of Grand Raiden for an object size of about 1 mm. © 2002 Elsevier Science B.V. All rights reserved.

Language：English Publishing type：Research paper (scientific journal)

Nucleon-nucleon decoupled dibaryons below the pion emission threshold have been investigated by the pd→pdX and pd→ppX reactions at E_p - 300 MeV. Such dibaryons are predicted to either decay into a deuteron or two nucleons by emitting a γ ray and consequently have a very narrow width of less than 1 keV. The experiment was carried out at the Research Center for Nuclear Physics employing a two-arm magnetic spectrometer. A mass resolution of 0.95 MeV and background-free condition have been achieved.

Language：English

The role of the Δ resonance has been discussed for the ^12,13,14C(p, π^-)^13,14,15O_g.s. reactions both experimentally and theoretically. Recent calculations suggested resonance effects in the energy dependence of the differential cross section that seem to contradict existing data. Since the available data points are limited, it is important to measure the energy dependence of the differential cross sections and the analyzing powers in order to better understand the still unclear reaction mechanism of the ground state (p, π^-) reactions. In the present paper, angular distributions of the differential cross sections and the analyzing powers were measured for ^12,13C(p, π^±) reactions at incident energies of 250, 300, and 350 MeV. Experimental results for the ¹²C(p, π^-)¹³O_g.s. reaction are compared with full-range distorted-wave Born approximation calculations.

Precise data on cross sections, analyzing powers and polarization transfer coefficients are measured for the dp elastic scattering at 270 MeV (135 MeV/nucleon) and compared to Faddeev calculations assuming the nd scattering with modern nucleon-nucleon (NN) forces including the 2π exchange Tucson-Melbourne (TM) three-nucleon (3N) force. Excellent fits are obtained for the cross sections and vector analyzing powers when the 3N force is included, while the fits are deteriorated for the tensor analyzing powers if the 3N force is included. A moderate fit is obtained for the polarization transfer coefficients. Based on theses results, one can conclude that the size of amplitudes of the TM-SN force may be adequate but the spin dependent part may be deficient. The cross sections and the vector analyzing powers for the nd elastic scattering at 250 MeV are measured for the first time. Backward cross sections are underestimated by the NN+3N force Faddeev calculations. This difference might be attributed to relativistic effects.

A method to prepare a windowless, self-supporting and low-cost ice target is described. The produced target was successfully used to measure the spectra of inelastic proton scattering from ¹⁶O. An ice target of about 30 mg/cm² worked stably. The target thickness was monitored for 7 hours by measuring p+p elastic scattering and no meaningful variation of the thickness was observed. No obvious effect of contaminations due to the congelation of residual gases on the target was detected. Since a thin ice target was made, measurements of charged decay particles in coincidence with inelastically scattered particles are possible.

Polarization correlation coefficients have been measured at RIKEN for the ³H^→e(d^→, p)⁴He reaction at intermediate energies (E_d = 270 MeV). We propose a model for the (d^→, p) reaction mechanism using the pd elastic scattering amplitude, which is rigorously determined with a Faddeev calculation and using modern NN forces. Our theoretical predictions for the deuteron polarization observables A_y, A_yy, A_xx and A_xz at E_d = 140, 200 and 270 MeV are given. The A_y observables agree qualitatively in shape with the new experimental data for the reaction ³He(d^→, p)⁴He.

The analyzing power, A_N, in inclusive charged-pion production has been measured using a ∼ 22-GeV/c transversely-polarized proton beam on a carbon target. A large AN was found for x_F > 0.5 and for 0.6 <P_T 1.2 GeV/c, with similar magnitudes and opposite sign for π⁺ and π^-. This mirror behavior and the magnitudes are similar to π^± production from 200-GeV/c polarized protons on a hydrogen target. The analyzing power for inclusive proton production has also been measured and is consistent with zero.

Language：English Publishing type：Research paper (scientific journal)

A new approach to study the high momentum component of deuteron D-state wave function by measuring the polarization correlation coefficient, C_// [= 1 + 1/4(A_yy + A_xx) + 3/4(C_y,y + C_x,x)], for the ³H^→e(d^→,p)⁴He reaction is proposed. The first measurement of C_// has been carried out at E_d = 270 MeV by using a newly constructed spin-exchange-type polarized ³He target. The obtained value is 0.223 ± 0.044(statistical) ± 0.037(systematic). DWBA calculations are unable to reproduce the present results. Each component of C _// is compared with data for the d+p backward scattering and the deuteron inclusive breakup. A similarity in polarization observables is found among these reactions.

Performance of the neutron polarimeter NPOL2 for (p→,n→) polarization transfer measurements Reviewed

404 ( 2-3 ) 355 - 372 1998.12

　More details

Language：English Publishing type：Research paper (scientific journal)

A high performance neutron polarimeter NPOL2 has been constructed to measure polarization transfer observables D_ij for neutron kinetic energies of T_n = 150-400 MeV. The NPOL2 system consists of 6 planes of two-dimensional position-sensitive neutron detectors with a size of 1 × 1 × 0.1 m³. Neutron polarization is determined from the azimuthal distribution of the elastic n→ + p scattering in the scintillator material. The effective analyzing powers (A_yeff) of NPOL2 have been calibrated by using the polarized neutrons from the 0° 2H(p→,n→)pp reaction at T_p = 146, 228, 296, 346 and 392 MeV as well as by using the polarized neutrons from the 0° ⁶Li(p→,n→)⁶Be(g.s.) reaction at T_p = 228 MeV. The A_y;_eff values of NPOL2 have reasonable values, typically 0.223 ± 0.012 and 0.132 ± 0.004 for (n→,n) and (n→,p) channels, respectively, at T_n = 291 MeV. The figure-of-merit value defined as ε_D.S.(A_y;_eff)² is over 4 × 10^-4 for the wide neutron kinetic energy region of T_n = 200-400 MeV, where ε_D.S is the double scattering efficiency.

Language：English Publishing type：Research paper (scientific journal)

The double differential cross sections for θ_lab between 0.0° and 14.7° and the polarization transfer coefficient D_NN(0°) for the ²⁷Al(^→p, ^→n) reaction have been measured at a bombarding energy of 295 MeV. A multipole decomposition technique is applied for the cross section data to extract L = 0, 1, 2, and 3 contributions. The Gamow-Teller (GT) strength B(GT) deduced from the L = 0 contribution is compared with the B(GT) values calculated in a full sd shell-model space. The sum of B(GT) values up to 20 MeV excitation is S_β = 4.0 ± 0.1 ± 0.1. A fairly large L = 0 contribution is observed in the continuum region up to 50 MeV, which could be in part ascribed to the quenched GT strength. A limit on the effect that the Δ(1232)-isobar nucleon-hole admixture has upon the GT strength is estimated.

　More details

Language：English Publishing type：Research paper (scientific journal)

The spin-flip probability for the charge-exchange reaction ²⁶Mg(³He,tγ)²⁶Al (1⁺; 1.06 MeV) has been measured at E = 53 MeV and θ_lab = 10°. The extracted value is 0.41 ± 0.04. A microscopic DWBA calculation with empirically determined effective interactions reproduces the observed cross sections fairly well but the spin-flip probability poorly. To supplement the (³He,tγ) study, the spin-flip probability has been measured for the same state by the charge-exchange (p,nγ) reaction at 35 MeV and θ_lab = 30° and found to be 0.52 ± 0.11. Though statistically not significant the lower value of S in the (³He,t) reaction may reflect on the more complex nature of this reaction at the present bombarding energy.

Spin-flip strength in the continuum and effective tensor interactions via polarization transfer DNN(0°) for (p→,n→) reactions at 295 MeV Reviewed

51 ( 6 ) 1995.1

　More details

Language：English Publishing type：Research paper (scientific journal)

The first measurements of DNN(0°) for (p→,n→) reactions at 295 MeV yield large negative values up to 50 MeV excitation for the Li6,11B,12C, C13(p→,n→) reactions, suggesting much stronger spin-flip strength than observed at lower bombarding energies. DWIA calculations using the Franey and Love (FL) 270 MeV interaction reproduce differential cross sections and DNN(0°) values, while the FL 325 MeV interaction yield DNN(0°) values less negative than the experimental values, suggesting that its exchange tensor part is too strong at large momentum transfer (Q3.4 fm-1).

The (d,2He) reactions on 24Mg, 26Mg and 28Si were studied at Ed = 270 MeV. The 0o cross sections obtained for the 1+ states from the 24Mg,28Si(d,2He) reactions show a good correlation with those from the mirror (p,n) reactions. Four peaks were identified in the 26Mg(d,2He)26Ne reactions as being due to the 1+ excitation. The B(GT+) values for these transitions were estimated and compared with the shell model prediction. © 1994.

Language：English Publishing type：Research paper (scientific journal)

It is theoretically shown that the tensor analyzing powers of the (→d, ²He) reaction contain essentially the same nuclear infrrmation as (→N, →N polarization transfer observables [1]. Considering its unique selectivities, ΔS =1, ΔT = 1 and ΔT_Z = +1, the (→d, ²He) reaction should be a useful tool for the study of spin-dipole state, particularly in identifying J^π (2^-, 1^- and 0^-). To confirm this point experimentally, A_xx, A_yy and A_y of the ¹²C(→d, ²He) ¹²B reaction have been measured at E_d = 270 MeV utilizing the newly constructed polarized ion source at RIKEN.

577 ( 1-2 ) 111 - 122 1994.9

　More details

Language：English Publishing type：Research paper (scientific journal)

The quasi-elastic scattering (QES) process has been studied for the (p, n) reaction at 300 and 400 MeV. Energy spectra for targets ranging from ²H to ^natPb have been obtained for a wide range of scattering angles corresponding to momentum transfers q = 1.0 - 2.4 fm^-1. Energy shift of the QES peak from that of ²H to higher excitation energy is observed for all targets studied, with a gradual increase with target mass reaching almost a constant value of ∼26 MeV beyond ¹²C. The mass dependence oo the effective neutron number (N_eff) for the (p, n) QFS process is well represented by N_eff = 0.85N^0.5 over a wide mass range from ²H to ^natPb except for ⁶Li, ⁷Li and ⁹Be which deviate significantly. The analyzing powers of the QES peak region for the ¹²C and ⁴⁰Ca targets are compared to those of the ²H(p, n) reaction at 300 and 400 MeV and found to be almost identical for q ≤ 1.5 fm^-1. Transverse polarization transfer coefficients at 0 degree D_NN(0°) have been measured for the 1p shell nuclei at 300 MeV. Large negative D_NN(0°) values are observed for the continuum region up to an excitation energy of 50 MeV irrespective of targets. The D_NN(0°) values observed for the GT transitions are around -0.28 which indicates the contribution from the tensor interactions. The DWIA calculations well reproduce the observed D_NN(0°) values.

Language：Others

Spin-dipole strengths and tensor correlation effects for ${}^{208}{
m Pb}(p,n)$ at 295 MeV
We performed the multipole decomposition analysis (MDA) for the ${}^{208}{
m 
Pb}(p,n)$ data in order to obtain the spin-dipole (SD) strengths separated into 
each $Delta J^{pi}$ contribution $dB({
m SD}_{Delta 
J^{pi } };omega)/domega$. 
The random phase approximation (RPA calculations reproduce the total SD 
strength reasonably well, whereas some discrepancies are found for separated SD 
strength. 
The centroids of the resonances are slightly lower and higher than the 
theoretical predictions for $1^-$ and $2^-$, respectively. 
These softening and hardening effects observed in $1^-$ an...

Differential cross section and analyzing power of the ${vec p}p{ o}ppπ^0$ reaction at a beam energy of 390 MeV

2008.4

　More details

Language：English

The differential cross section and analyzing power $A_y$ of the ${vec 
p}p{ o}pp{pi}^0$ reaction have been measured at RCNP in coplanar geometry at 
a beam energy of 390 MeV and the dependence on both the pion emission angle and 
the relative momentum of the final protons have been extracted. The angular 
variation of Ay for the large values of the relative momentum studied here 
shows that this is primarily an effect of the interference of pion s- and 
p-waves and this interference can also explain the momentum dependence. Within 
the framework of a very simple model, these results would sugge...

$2α+t$ cluster structure in $^{11}$B

2007.3

　More details

Language：English

The cluster structures of the excited states in $^{11}$B are studied by 
analyzing the isoscalar monopole and quadrupole strengths in the 
$^{11}$B($d$,$d'$) reaction at $E_d=200$ MeV. The excitation strengths are 
compared with the predictions by the shell-model and antisymmetrized 
molecular-dynamics (AMD) calculations. It is found that the large monopole 
strength for the $3/2^-_3$ state at $E_x=8.56$ MeV is well described by the AMD 
calculation and is an evidence for a developed $2alpha+t$ cluster structure.

The cross section of the ${}^{16}{

scattering was measured at a bombarding energy of 295 MeV in the momentum 
transfer range of $1.0 mathrm{fm^{-1 } }$ $le$ $q_{

mathrm{fm^{-1 } }$. 
The isovector $0^-$ state at $E_x$ = 12.8 MeV is clearly separated from its 
neighboring states owing to the high energy resolution of about 30 keV. 
The cross section data were compared with distorted wave impulse 
approximation (DWIA) calculations employing shell-model wave functions.

We have measured the cross sections and analyzing powers Ay and Ayy for the elastic and inelastic scattering of deuterons from the 0+(g.s.), 2+(4.44 MeV), 3-(9.64 MeV), 1+(12.71 MeV), and 2-(18.3 MeV) states in 12C at an incident energy of 270 MeV. The data are compared with microscopic distorted-wave impulse approximation calculations where the projectile-nucleon effective interaction is taken from the three-nucleon t-matrix given by rigorous Faddeev calculations presently available at intermediate energies. The agreement between theory and data compares well with that for the (p, p′) reactions at comparable incident energies/nucleon. © 2002 Elsevier Science B.V. All rights reserved.

The analyzing power of ${vec p}p o pp{pi}^0$ reaction has been measured at 
the beam energy of 390 MeV. The missing mass technique of final protons has 
been applied to identify the $pi^0$ production event. The dependences of the 
analyzing power on the pion emission-angle and the relative momentum of the 
protons have beenobtained. The angular dependence could be decomposed by the 
Legendre polynomial and the relative contribution of the $P_{21}$ to $P_{11}$ 
function is less than 20%. The P-state amplitude is found to be the dominant 
component of the $pi$ production near the threshold. The...

Thin ice target for 16O(p,p′) experiment

2001.2

　More details

Language：English

A method to prepare a windowless, self-supporting and low-cost ice target is described. The produced target was successfully used to measure the spectra of inelastic proton scattering from 16O. An ice target of about 30 mg/cm2 worked stably. The target thickness was monitored for 7 hours by measuring p+p elastic scattering and no meaningful variation of the thickness was observed. No obvious effect of contaminations due to the congelation of residual gases on the target was detected. Since a thin ice target was made, measurements of charged decay particles in coincidence with inelastically scattered particles are possible.

Reaction mechanism and characteristics of T_{20} in d + ^3He backward elastic scattering at intermediate energies
For backward elastic scattering of deuterons by ^3He, cross sections sigma 
and tensor analyzing power T_{20} are measured at E_d=140-270 MeV. The data are 
analyzed by the PWIA and by the general formula which includes virtual 
excitations of other channels, with the assumption of the proton transfer from 
^3He to the deuteron. Using ^3He wave functions calculated by the Faddeev 
equation, the PWIA describes global features of the experimental data, while 
the virtual excitation effects are important for quantitative fits to the 
T_{20} data. Theoretical predictions on T_{20}, K_y^y (polarizatio...
