Global optical potentials for elastic p + Ca40 scattering using the Dirac equation

Abstract

We present the first global relativistic optical-model treatment of proton-nucleus elastic scattering. Energy-dependent optical potential parameters for the Lorentz vector and scalar potentials of Dirac phenomenology are given. Several different assumptions regarding the optical-model energy dependence are considered. Constraints from relativistic mean-field theory are presented. © 1987 The American Physical Society.
