3P2-3F2 pairing in neutron matter with modern nucleon-nucleon potentials

We present results for the P-3(2)-F-3(2) pairing gap in neutron matter with several realistic nucleon-nucleon potentials, in particular with recent phase-shift-equivalent potentials. We find that their predictions for the gap cannot he trusted at densities above rho approximate to 1.7 rho(0), where po is the saturation density for symmetric nuclear matter. In order to make predictions above that density, potential models which fit the nucleon-nucleon phase shifts up to about 1 GeV are required. [S0556-2813(98)06010-5].
