N N potentials from inverse scattering in the J-matrix approach

An approximate inverse scattering method 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 S-1(0) and P-3(2)-F-3(2) channels and neutron-proton in the S-3(1)-D-3(1) channel elastic scattering. In the latter case the deuteron wavefunction of a realistic np potential was used as input.
