Elastic Scattering of Some Halo Nuclei of Proton at Energies Below 200 MeV/N

Abstract

A microscopic approach was used to analyse the investigation of the elastic scattering of protons on 4,6,8 He at energies up to 200 MeV/N. The microscopic single folding (SF) and São-Paulo (SP) potentials were used to generate the real part of the optical model potential, and the Woods-Saxon form was used to phenomenologically compute the imaginary part. Three distinct nuclear densities (GG, GO, and G2S) of 4,6,8 He and Gaussian form effective NN interactions were used to determine the SF potential. A renormalization factor 𝑁𝑅 of the folded real potential as well as the imaginary and spin-orbit potentials were among the free parameters used in the investigation, which was carried out using the FRESCO code. In addition, the overall reaction cross-sections 𝜎𝑅 in the three densities (GG, GO, and G2S) and the related real and imaginary volume integrals of interacting nucleon pairs were examined. The differential and reaction cross-section values that were obtained were in fair accord with the experimental data.
