Abstract
Modern Brueckner-Hartree-Fock (BHF) calculations are very successful in describing various properties of symmetric and asymmetric nuclear matter. Within BHF theory, a microscopic optical potential (MOP) for nucleon-nucleus scattering is developed. First, we parametrize the energy and density dependence of complex optical potentials in nuclear matter based on BHF calculations, and then we construct the MOP for finite nuclei with the local density approximation extended to include the finite-range effects. The density distribution and the spin-orbit contribution are calculated from the Hartree-Fock approximation with the LNS5 Skyrme interaction, the latter being constrained by the BHF results. The central real and imaginary potentials turn out to be quantitatively consistent with the phenomenological global Koning-Delaroche potentials. The performance of MOP is evaluated by considering neutron and proton scattering on . The elastic-scattering differential cross sections, analyzing powers, total and reaction cross sections are analyzed in the energy range below 200 MeV. A good agreement between the theoretical results and the measurements is achieved. Since our results are presented in analytic forms, they can thus be used easily in the analysis of the experimental data of the nucleon scattering on exotic nuclei.
