Abstract

We study the connection between relativistic mean field models and the bare nucleon-nucleon interaction. We start from a bare interaction, and by employing a G-matrix formalism we derive a density dependent realistic interaction in the medium. We introduce a one-boson-exchange potential and we extract the masses and the coupling strengths of the meson fields through a fit to the G-matrix potentials. The parameters and their density dependence are compared with those of other one-boson-exchange parametrizations.
