Energy-dependent microscopic optical potential for scattering of nucleons on light nuclei

We present an energy-dependent microscopic optical model potential for elastic scattering of nucleons on light nuclei. The single-folding model is used for the real part of the optical potential (OP), while the imaginary part is derived within the high-energy approximation theory. The energy dependence of the OP is determined from the parameterization of the volume integrals those calculated from the best-fit OP that fit the experimental data of the cross sections and analyzing powers. This energy-dependent OP is successfully applied to analyze the proton elastic scattering of 4,6,i8He, 6,7Li, and 9,10Be nuclei at low and intermediate incident energies up to 200MeV/nucleon. (orig.)
