CHIRAL BACKGROUND FOR THE 2-PION EXCHANGE NUCLEAR-POTENTIAL - A PARAMETRIZED VERSION

We argue that the minimal chiral background for the two-pion exchange nucleon-nucleon (NN) interaction has nowadays a rather firm conceptual basis, which entitles it to become a standard ingredient of any moder n potential. In order to facilitate applications, we present a paramet rized version of a configuration space potential derived previously. W e than use it to assess the phenomenological contents of some existing NN potentials.
