Taylor series expansion, Screened Coulomb plus non-local potential, energy-momentum dependent potential, phase parameters, cross-sectionsAbstract
Energy-momentum-dependent potentials corresponding to a separable non-local potential and a local potential are created to explore nucleon-nucleon and nucleon-nucleus systems. There is either no hardcore or a quasi-hard core in the created local potentials. Using the phase function method, elastic scattering phase shifts are calculated for the nucleon-nucleon and alpha-nucleon systems, and the results show reasonable agreement with experimental data. Utilizing the s-wave phase parameters, the scattering cross sections are also estimated.
