Comparison of potential models with the pp scattering data below 350 MeV

Abstract

We calculate the chi**2 of various NN potential models with respect to the pp scattering data. We find that only the potential models which were explicitly fitted to the pp data give a reasonable description of these data. Most models give a pretty large chi**2 on the very low-energy pp data, due to incorrect 1S0 phase shifts.
