Proton scattering of helium isotopes using an energy-dependent folded potential

摘要

The proton elastic scattering data on helium isotopes at different energies are analyzed using the folding optical model with the distorted wave born approximation. The obtained results of the differential and the reaction cross sections are in good agreement with the available experimental data. The volume integrals of the best-fit OP parts have systematic energy dependencies, and they are parameterized in empirical formulas. Then, the energy dependence of the OP is determined from the parameterization of the volume integrals.
