Abstract
An energy momentum-dependent potential is considered to study nucleon-nucleon, nucleon-nucleus and nucleus-nucleus elastic scattering by exploiting the variable phase method to potential scattering. The velocity dependent potential, equivalent to Graz separable potential, has the ability to reproduce the correct nature and numerical values of the NN phase parameters up to 400 MeV. Also it works equally well for alpha-nucleon and alpha-alpha systems up to few higher partial waves. Our results are in close conformity with the previous theoretical and experimental data. For alpha-alpha scattering we have treated only s-wave case.
