1. Toshimasa FURUTA, Yuji Yamaguchi, Yusuke Uozumi, Yosuke Iwamoto, Yusuke Koba, Elena Velicheva, Vladimir Kalinnikov, Zviadi Tsamalaidze, Petr Evtoukhovitch, Double-differential cross sections for charged particle emissions from α particle impinging on Al at 230 MeV/u, Journal of Nuclear Science and Technology, https://doi.org/10.1080/00223131.2023.2294192, 61, 2, 230-236, 2023.12, Charged particle production from α particle fragmentation reactions was investigated experimentally by measurement of 230-MeV/u α particles bombarding an aluminum target. Double differential cross sections were measured for each ejectile of p, d, t, 3He, and 4He using counter telescopes composed of Si surface barrier detectors and crystal scintillators, which were located at laboratory angles between 15° and 60°. The obtained data were analyzed for comparison with data observed at lower incident energies. The results found the following common characteristics: (1) spectra of proton- and neutron-emission are similar in high energy region at forward angle, (2) triton-to-3He ratio of α-breakup yield is 1:2, which is similar to lower incident energy experiment, and (3) the shape of broad peak formed by 3He and α particles could be explained by the process with collision between induced α particle and target nucleus..
2. Masahiro Nakano, Yuji Yamaguchi, Yusuke Uozumi, Effects of deuteron potentials on deuteron-induced nonelastic cross sections based on the intranuclear cascade model, Physical Review C, https://doi.org/10.1103/PhysRevC.108.044615, 108, 044615, 2023.10, The aim of this paper is to investigate how the choice of deuteron potential affects the nonelastic cross sections of 12C, 40Ca, 58Ni, and 208Pb in the low-energy region below 200 MeV within the extended framework of the intranuclear cascade model, in which a three-body proton-neutron-target system is introduced to incorporate naturally the decomposition and capture reactions from weakly bound deuterons. To determine an appropriate potential for the two nucleons of the deuteron, we compare two phenomenological potentials with the Gaussian potential that we have used previously. Specifically, we examine the Reid and Coester-Yen soft-core potentials and find that they give reduced nonelastic cross sections. To investigate the role of the potential, we separate it into the tail region in the outer part and the soft-core region in the central part. By using a gluing method to connect the Gaussian potential smoothly to the Yukawa tail, we show that the tail has no appreciable effect for any of the targets. On the other hand, by adding a soft core to the ordinary Gaussian potential, we show that the soft core has appreciable effects, especially in heavier nuclei such as 208Pb, the reason being the reduced breakup process with a soft-core potential from the deuteron rotation due to the Coulomb potential. The results of this study show that while the Yukawa tail has no appreciable effect, soft-core potentials tend to give reduced nonelastic cross sections, especially for heavy nuclei..

Yusuke Uozumi, Toshimasa Furuta, Yuji Yamaguchi, Heishun Zen, Toshiteru Kii, Hideaki Ohgaki, Elena Velicheva, Vladimir Kalinnikov, Zviadi Tsamalaidze, Petr Evtoukhovitch, Study of crystalline scintillator response with development of single-electron beam of 2–6 MeV at KU-FEL, Journal of Nuclear Science and Technology , https://doi.org/10.1080/00223131.2023.2172087, 2023.02,
A single-electron measurement technique is developed at the Kyoto University Free Electron Laser (KU-FEL) facility, and the responses of crystalline scintillators to electrons of 2–6 MeV are investigated. Precise control of the thermionic cathode of the radio frequency gun and the bending magnet allow a low-intensity monoenergetic electron beam to be produced for single-electron measurements. The pulse-height distributions and energy proportionalities are measured for three scintillators (PWO, LaBr3:Ce, and LYSO:Ce). The shapes of the observed pulse-height distributions almost match those of deposited energy distributions calculated by Monte Carlo simulations, thereby making it possible to deduce the energy deposition to the detectors, and all the scintillators show good proportionalities..
4. Masahiro Nakano, Yuji Yamaguchi, Yusuke Uozumi, Deuteron-induced nonelastic cross sections based on the intranuclear cascade model with independent incident particles under interaction potentials, Physical Review C, https://doi.org/10.1103/PhysRevC.106.014612, 106, 014612, 2022.07, Deuteron-induced nonelastic cross sections are studied in an extended intranuclear cascade (INC) model. A three-body framework of proton, neutron, and target is introduced into the INC model to incorporate naturally the decomposition and capture reactions from weakly bound deuterons. This framework includes three types of interaction potential, namely proton-target, neutron-target, and proton-neutron, the last of which causes the two nucleons in the deuteron to oscillate and play an important role in its breakup. The calculated results reproduce well the experimental data for 12C, 40Ca, 58Ni, and 208Pb targets with almost the same parameters as those determined previously for nucleon-induced nonelastic reactions. It is found that the contribution of the two-nucleon collision process increases with target size, that the contribution of the capture processes is limited to a narrow region at low energy for lighter targets, and that the contribution of the breakup process is relatively small compared to other processes. It is also concluded that discrete-level-constraint effects dominate in the low-energy region for light nuclei such as 12C, while Coulomb effects dominate in the low-energy region for heavy nuclei. This result is consistent with the INC model of nucleon incidence, which explains well the nucleon-induced nonelastic cross sections at low energies..
5. Vladimir Kalinnikov, Elena Velicheva, Yusuke Uozumi, Comparison of the Scintillation Properties of Long LYSO:Ce Crystals from Different Manufacturers, Physics of Particles and Nuclei Letters, 10.1134/S1547477121040105, 18, 4, 457-468, 2021.05, Cerium-doped lutetium yttrium oxyorthosilicate (LYSO:Ce) crystals are known to have considerable variation in scintillation light yield. Thus, the use of long LYSO:Ce crystals in energy measurements requires improved uniformity to realize high resolution. As it is known that differences in crystal characteristics can originate from differences in manufacturing techniques using the Czochralski method, it is useful to measure and compare the non-uniformity of LYSO:Ce crystals from different manufacturers. Comprehensive comparison of such crystals can be achieved using two methods, namely, gamma spectroscopy and optical spectroscopy. In this study, we examined two long crystals obtained from Saint-Gobain (France) and JT Technology Co. Ltd. (China). The Saint-Gobain crystal was found to have a more uniform distribution of scintillation properties and to contain fewer optical traps and crystal structure defects..
6. Masahiro Nakano, Yuji Yamaguchi, Yusuke Uozumi, New empirical formula for nucleon-induced nonelastic cross sections based on two physical effects, Physical Review C, https://doi.org/10.1103/PhysRevC.103.044608, 103, 044608, 2021.04, A simple universal parametrization of nucleon-induced nonelastic cross sections is presented for a wide range of targets that is valid for the entire energy range from zero to a few gigaelectronvolts. We review several early studies by Letaw et al., Pearlstein, Shen, Niita et al., and Tripathi et al., and our proposed approach differs completely from the formulas therein. The present formula is constructed based on recently discovered physical effects involving Coulomb repulsion and the discrete-level constraint and is based on the assumption that cross sections are continuous in both incident energies and targets. Our formula is given by a set of smooth functions of the mass number, which differs from the best formula to date by Tripathi et al. To compare our formula precisely with that by Tripathi et al., we proposed the relative error index, which indicates the relative error between experimental data and predicted values. For the 12C, 27Al, 56Fe, natAg, natCd, natSn, 197Au, and 208Pb targets used in this paper, the corresponding relative error indices show clearly that our formula is superior to that by Tripathi et al..

9. Y. Yamaguchi, G. Watanabe, T.Ageishi, T.Katayama, T. Ogawa, Y. Uozumi, Development of INC-ELF version 2 and incorporation into PHITS: Extension to lower incident energies down to 30 MeV, Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, https://doi.org/10.1016/j.nimb.2020.07.012, 479, 15, 233-239, 2020.07, Version 2 of the Intranuclear Cascade with Emission of Light Fragments (INC-ELF) code is developed and incorporated into the Particle and Heavy Ion Transport code System (PHITS). The aim of INC-ELF2 is to expand it to the lower incident-energy range of 30–200 MeV, where the original INC theory is not applicable. The refinement of the code is based faithfully on the results of basic research on direct reactions within the framework of the INC model. INC-ELF2 can deal with the emission of light fragments from nuclear reactions induced by protons and neutrons. Double-differential cross-sections are calculated by a two-step model combining INC-ELF2 and GEM (generalized evaporation model) in PHITS, and they are compared with experimental data to examine the predictive ability. Excellent agreement is confirmed for various reactions over a wide range of target masses and over the incident-energy range of 30–200 MeV..
10. Yusuke Uozumi, Yuki Fukuda, Yuji Yamaguchi, Gaku Watanabe, Masahiro Nakano , Direct pickup and knockout processes in inclusive (p,αx) reactions from 42 to 300 MeV, Physical Review C, https://doi.org/10.1103/PhysRevC.102.014604, 102, 014604, 2020.07, Inclusive (p,αx) reactions from 42 to 300 MeV are investigated to quantitatively understand the roles of direct pickup and knockout processes. These two processes as well as indirect pickup are incorporated into the intranuclear cascade model. Calculations followed by the evaporation model successfully explain the double-differential cross-section spectra in terms of both shape and magnitude. Direct pickup occupies the low excitation energies of the spectra, and knockout appears between the direct pickup and evaporation regions. The contribution of knockout is negligible below 100 MeV, increases to be comparable with that of direct pickup at 160 MeV, and is dominant above 200 MeV. Indirect pickup shows an important contribution at 300 MeV. The direct pickup and knockout processes show decreasing trends of incident-energy dependence, common to targets ranging from 12C to 209Bi. However, the decrease of direct pickup is much faster than that for knockout..

Masahiro Nakano, Yuji Yamaguchi, Yusuke Uozumi, Two effects in nucleon-induced nonelastic cross sections based on the intranuclear cascade model, Physical Review C, https://doi.org/10.1103/PhysRevC.102.024608, 102, 024608, 2020.08, Proton- and neutron-induced nonelastic cross sections for 12C, 27Al, 56Fe and 208Pb are investigated in the low energy region from 100MeV down to nearly zero MeV based on a framework of the intranuclear cascade (INC) model. It is shown that the INC model can reproduce the experimental data both for the proton- and neutron-induced nonelastic cross sections of a wide range of targets in a systematic way, and that the crucial point is to include the transition probability of the excited particles originated from the discrete level constraint (DLC). On the basis of the reliability of INC calculation, we analyze the two effects of the discrete level constraint and Coulomb repulsion separately in the proton and for neutron injection cases, and we elucidate the domain of the target mass and the kinetic energy where two effects play important roles..

Masahiro Nakano, Yuji Yamaguchi, Yusuke Uozumi, Scale breaking in the low-energy proton-induced nonelastic cross sections, Physical Review C, https://doi.org/10.1103/PhysRevC.101.044616, 101, 044616, 1-7, 2020.04, Proton-induced nonelastic cross sections for 12C, 27Al, 56Fe, and 208Pb are investigated in a low-energy region below 100 MeV down to nearly 0 MeV based on a framework of an intranuclear cascade (INC) model. We point out that there is a scaling among the calculations including the Coulomb repulsion; two cases are shown: One is the scaling of the trajectories with different impact parameters, and the other is the incident-energy dependence of the cross sections. We point out for the first time that the calculated cross sections by the usual INC model follow a scaling and the discrepancy between the calculated cross sections and the experimental data indicates the scale breaking and that, for the explanation of the scale breaking, it is essential to include the discrete level constraints in addition to the Coulomb repulsion in the INC model..

In this method, the coefficient is defined as the ratio of the cross section of the proton-nucleus reaction to that of the neutron-nucleus reaction and is calculated by using empirical equations for the cross sections with no free parameters. The determined coefficient is incorporated into an intranuclear cascade model followed by an evaporation model, and the double-differential cross sections are calculated for (p,p′x) reactions around 50 MeV on heavy targets with A≥120. The present results agree well with experimental observations. Remarkably, the spectra for 209Bi and 197Au are accounted for even though the evaporation contributions are negligibly small..
