NN potentials from inverse scattering in the J-matrix approach

Abstract

An approximate inverse scattering method [7,8] has been used to construct separable potentials with the Laguerre form factors. As an application, we invert the phase shifts of proton-proton in the ${}^1{S}_0$ and ${}^3{P}_2{-}^3{F}_2$ channels and neutron-proton in the ${}^3{S}_1{-}^3{D}_1$ channel elastic scattering. In the latter case the deuteron wave function of a realistic $np$ potential was used as input.
