Realistic effective interactions for nuclear systems

Abstract

A review of perturbative many-body descriptions of several nuclear systems is presented in this report. Examples of systems considered are symmetric and asymmetric nuclear matter and finite nuclei with few valence particles. Our many-body description starts with the most recent meson-exchange potential models for the nucleon-nucleon interaction, an interaction which in turn is used in our perturbative schemes to evaluate the effective interaction for finite nuclei and infinite nuclear matter. A unified perturbative approach based on time-dependent perturbation theory is elaborated. For finite nuclei we present new results for the effective interaction and the energy spectra in the mass areas of oxygen, calcium and tin. © 1995.
