Calculations of $^{6}$He+p elastic scattering cross sections using folding approach and high-energy approximation for the optical potential

摘要

Calculations of microscopic optical potentials (OP's) (their real andimaginary parts) are performed to analyze the $^6$He+p elastic scattering dataat a few tens of MeV/nucleon (MeV/N). The OP's and the cross sections arecalculated using three model densities of $^6$He. Effects of the regularizationof the NN forces and their dependence on nuclear density are investigated.Also, the role of the spin-orbit terms and of the non-linearity in thecalculations of the OP's, as well as effects of their renormalization arestudied. The sensitivity of the cross sections to the nuclear densities wastested and one of them that gives a better agreement with the data was chosen.
