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

Abstract

As a follow-up on our earlier paper we calculate the ${\chi }^2$ of various $NN$ potential models with respect to the $np$ scattering data. We find that only the most recent potential models give a reasonably good description of these data. Almost none of the potentials is truly an $NN$ potential in the sense that it gives a good description of both $pp$ and $np$ scattering simultaneously.
