K. Hagino and S. Sakaguchi, Subbarrier fusion reactions of an aligned deformed nucleus, Physical Review C, 10.1103/PhysRevC.100.064614, 100, 2019.12, We discuss heavy-ion fusion reactions of a well-deformed odd-mass nucleus at energies around the Coulomb barrier. To this end, we consider the 16O+165Ho reaction and take into account the effect of deformation of 165Ho using the orientation average formula. We show that fusion cross sections are sensitive to magnetic substates of the target nucleus, and cross sections for the side collision, which are relevant to a synthesis of superheavy elements, may be enhanced by a factor of around two by aligning the deformed target nuclei. We also discuss the effect of alignment on the fusion barrier distribution. We find that, for a particular choice of alignment, the shape of barrier distribution becomes similar to a typical shape of barrier distribution for a deformed nucleus with a negative hexadecapole deformation parameter, β4, even if the intrinsic β4 is positive in the target nucleus.. |

Zenihiro, Proton elastic scattering at 200 A MeV and high momentum transfers of 1.7-2.7 fm -1 as a probe of the nuclear matter density of 6 He, Progress of Theoretical and Experimental Physics, 10.1093/ptep/pty048, 2018, 5, 2018.05, Differential cross sections of p-6He elastic scattering were measured in inverse kinematics at an incident energy of 200 A MeV, covering the high momentum transfer region of 1.7-2.7 -1. The sensitivity of the elastic scattering at low and high momentum transfers to the density distribution was investigated quantitatively using relativistic impulse approximation calculations. In the high momentum transfer region, where the present data were taken, the differential cross section has an order of magnitude higher sensitivity to the inner part of the 6He density relative to the peripheral part (15:1). This feature makes the obtained data valuable for the deduction of the inner part of the 6He density. The data were compared to a set of calculations assuming different proton and neutron density profiles of 6He. The data are well reproduced by the calculation assuming almost the same profiles of proton and neutron densities around the center of 6He, and a proton profile reproducing the known point-proton radius of 1.94 fm. This finding is consistent with the assumption that the 6He nucleus consists of a rigid α-like core with a two-neutron halo.. |
