Microscopic Study of Nucleon-⁴He Scattering and Effective Nuclear Potentials

Abstract

The nucleon-⁴He scattering in a wide energy region is quantitatively investigated using single channel resonating group method with the realistic effective two-body nuclear potential which includes the central, tensor and spin-orbit parts. It is shown that the empirical phase shifts and the experimental data are very well reproduced over that energy range and the N-⁴He elastic scattering is quantitatively understood by means of the microscopic theory with the realistic effective potential. In the p-⁴He scattering at high energies, an imaginary potential (volume type, surface type and non-local terms) is introduced in relation to the reaction process to the d-³He channel. Phase shifts, differential cross sections, polarizations, total cross sections and reaction cross sections are calculated at many incident energies up to 85 MeV. It is clarified that the parity and energy dependences of the nucleon-⁴He interaction are important to reproduce various experimental data and the tensor part of the realistic nuclear potential is mainly concerned in such properties. The odd-state part of the realistic effective nuclear potential is well determined through the analysis of the low energy phenomena of the n-⁴He scattering. An equivalent local potential with the parity dependence between the nucleon and ⁴He is also constructed.
