摘要：

We employ the single folding model to calculate the optical potential (OP) for the p+O-16 scattering system, in which the exchange term of the OP is nonlocal. In most studies, this term is approximated to a local form to simplify the calculations. In this work, the folding OP, including the nonlocal exchange term, is constructed based on the CDM3Y3 effective nucleon-nucleon (NN) interaction. The Schr & ouml;dinger equation for the nucleon-nucleus scattering with the nonlocal OP is solved exactly using the Lagrange-mesh R-matrix method. By comparing the scattering cross sections calculated with the nonlocal potential and the localized approximation, we can assess the impact of the nonlocality effects in proton-nucleus elastic scattering. The calculated results demonstrate that the nonlocality effect of the OP significantly influences the low-energy elastic scattering cross sections of p+O-16 .
