Self-consistent and optical nucleon potentials for positive and negative energies

The properties of Hartree-Fock potential coinciding with self-consistent nucleon potential and the real part of optical nucleon potential for global averaging are investigated with allowance for the velocity-dependent terms of nucleon-nucleon forces and the nonlocality effects. The characteristics of effective energy-dependent Hartree-Fock potential are first analyzed for negative nucleon energy values. It is demonstrated that the shape of this potential changes as nucleon energy changes from negative to positive values. The conditions of applicability of semiclassical approach are found
