Analytical expressions for nucleon-nucleon phase shift at high energy using separable potential

We obtain analytical expressions for the two-body T-martix and phase shift at high energy (~350 ??????) scattering using nonlocal rank-two separable potential of Mongan type. The potential parameters are adjusted by fitting the available experimental nucleon-nucleon high energy scattering phase shift data for two single channels 1D2 and 1P1 with the corresponding derived analytical expressions.The results indicate that the analytical expressions obtained for the phase shifts are succsseful in repoducing the nucleon-nucleon scattering data.
