INVESTIGATION OF OPTICAL-POTENTIAL WITH RELATIVISTIC EFFECTIVE INTERACTION

The relativistic microscopic optical potential is studied in terms of the effective interaction, where the two-body correlations in the relativistic G-matrix are parametrized by the effective meson exchange. Various meson contributions and correlation effects are discussed. It is found that the calculated scalar and vector potentials of a nucleon in the nuclear medium with the correlations are a hundred MeV weaker than those obtained in the sigma-omega model and have rather good behaviour of the energy and density dependence. The resulting Schrodinger equivalent potentials are in good agreement with phenomenological ones over a very large energy region.
