Exponential potential of NN interactions with forbidden state in S - wave

Abstract

An exponential version of a deep nucleon-nucleon potential involving forbidden states and a tensor component is proposed. The parameters of interaction are chosen by fitting the low-energy characteristics and phase shifts of np scattering at energies up to 500 MeV. Such potential have not node in D wave as against earlier proposed.
