Partly Nonlocal Potentials in Nuclear Matter

Abstract

A set of phase-equivalent partly nonlocal two-nucleon potentials in the s state are constructed, with short range separable-type repulsion superimposed on a local attractive potential of longer range. Nuclear matter calculations with potentials of this type reveal qualitative differences when the results are compared with those obtained from phase-equivalent rank-two separable potentials. These differences are linked to the different behaviors of the two-body bound state wave functions generated by an attractive local potential and its phase-equivalent separable counterpart.
