The proton optical potential for $^{53}$Cr at low and medium energies

Parameters have been determined for the optical potential OP providing close reproduction of the observed differential cross sections for elastic scattering and polarization, as well as the energy dependence of the total reaction cross section. The energy dependence has been determined for the proton OP parameters for $^{53}$Cr, as well as the energy dependence of the elastic-scattering cross section involving the compound nucleus and the dependence of the exchange integral for the imaginary potential per nucleon on the incident-proton energy.
