“…The OM description of the elastic proton scattering from 48 Ca, 90 Zr, 120 Sn, and 208 Pb targets at incident proton energy of 40 MeV given by the three global proton-nucleus OP's are shown in Fig. 1 together with the measured data [34,35]. Except for some underestimation of the calculated elastic cross section in the p+ 48 Ca case, the overall OM description of the considered elastic scattering data is reasonable.…”

A consistent folding model analysis of the ( S = 0, T = 1) charge exchange (p, n) reaction measured with 48 Ca, 90 Zr, 120 Sn, and 208 Pb targets at the proton energies of 35 and 45 MeV is done within a two-channel coupling formalism. The nuclear ground state densities given by the Hartree-Fock-Bogoliubov formalism and the density-dependent CDM3Y6 interaction were used as inputs for the folding calculation of the nucleon optical potential and (p, n) form factor. To have an accurate isospin dependence of the interaction, a complex isovector density dependence of the CDM3Y6 interaction has been carefully calibrated against the microscopic Brueckner-Hartree-Fock calculation by Jeukenne, Lejeune, and Mahaux before being used as folding input. Since the isovector coupling was used to explicitly link the isovector part of the nucleon optical potential to the cross section of the (p, n) reaction exciting the 0 + isobaric analog states in 48 Sc, 90 Nb, 120 Sb, and 208 Bi, the newly parametrized isovector density dependence could be well tested in the folding model analysis of the (p, n) reaction. The isospin-and density-dependent CDM3Y6 interaction was further used in the Hartree-Fock calculation of asymmetric nuclear matter, and a realistic estimation of the nuclear symmetry energy was made.

“…Analysis of the p+ 8 He elastic scattering, which will be reported elsewhere, revealed that those of 8 He are 2.22±0.27 fm and 2.02±0.52 MeV, respectively, which are similar to those of 6 He. Compared with these values, LS amplitudes of neighboring even-even stable nuclei [13,14,15] and global optical potentials [16,17] are considerably different. The LS amplitudes of stable nuclei are distributed at around 5 MeV, whereas those of 6 He and 8 He are as small as 1.3 and 2.0 MeV.…”

Abstract. The vector analyzing power has been measured for the elastic scattering of neutronrich 6 He and 8 He from polarized protons at 71 MeV/A making use of a newly constructed solid polarized proton target operated in a low magnetic field of 0.1 T and at a relatively high temperature of 100 K. An optical model analysis revealed that the spin-orbit potentials for 6 He and 8 He are characterized by shallow and long-ranged shape compared with the global systematics of stable nuclei. Such a characteristics reflect a diffused density distribution of the neutron-rich isotopes.

The vector analyzing power has been measured for the elastic scattering of neutron-rich 6 He from polarized protons at 71 MeV/nucleon making use of a newly constructed solid polarized proton target operated in a low magnetic field and at high temperature. Two approaches based on local one-body potentials were applied to investigate the spin-orbit interaction between a proton and a 6 He nucleus. An optical model analysis revealed that the spin-orbit potential for 6 He is characterized by a shallow and long-ranged shape compared with the global systematics of stable nuclei. A semimicroscopic analysis with a α+n+n cluster folding model suggests that the interaction between a proton and the α core is essentially important in describing the p+ 6 He elastic scattering. The data are also compared with fully microscopic analyses using non-local optical potentials based on nucleon-nucleon g-matrices.
