Abstract

Various versions of infinite nuclear matter reaction matrix elements (t‐matrix elements) were generated from free NN potentials. Most emphasis is put on calculations with the momentum dependent Paris potential as input. Thereupon is parametrized a complex energy and density dependent interaction (25‐500 MeV) with convenient Yukawa‐form factors to serve as effective interaction. It is the driving two‐body transition operator in applications to finite nuclei using a local density approximation. Studies concentrate on elastic channel microscopic optical model potential and its general structure as compared to phenomenological potentials. Further detailed checks on our effective interactions were performed with exemplary studies of (p,p′) transitions.
