Self-consistent single-nucleon potential at positive energy produced by semi-realistic interaction and its examination via nucleon-nucleus elastic scattering

Abstract
Based on the variational principle, self-consistent single-particle (s.p.) potentials at positive energies are discussed, which correspond to the real part of the optical potential as the single folding potential (SFP). The nuclear-matter s.p. potential produced by the semi-realistic nucleonic interaction M3Y-P6, which has links to the bare nucleonic interaction, resembles those extracted from the empirical optical potential Applying M3Y-P6 both to the self-consistent mean-field calculations for the target nucleus and to the SFP for the scattered nucleon, we find that the differential cross-sections of the nucleon-nucleus elastic scattering are reproduced almost comparably to the empirical potentials up to incident energy. The results demonstrate that the s.p. potential compatible with available experimental data can be derived from a single energy-independent effective interaction in this wide energy range.
