In order to facilitate applications, we present a parametrized version of a configuration space potential derived previously. We then use it to assess the phenomenological contents of some existing NN potentials. © 1995 The American Physical Society.531-538engArtigo10.1103/PhysRevC.52.5312-s2.0-4243902605
