Description
Summary:The Dirac equation-based (DEB) optical potential is used to study the elastic scattering cross section using entire energy range suitable for the relativistic treatment of proton. An effective core potential correction term arising from the second order Dirac equation is calculated for Si, Ca and Ti. From this study, we draw the corrected variation of the interaction potential as a function of the distance between two interacting nucleons over an energy range of 16–1044 MeV consistent with theoretical nuclear concepts.
