A microscopic approach was used to analyse the investigation of the elastic scattering of protons on ^4,6,8He 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 ^4,6,8He  and Gaussian form effective NN interactions were used to determine the SF potential. A renormalization factor 𝑁_𝑅 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 𝜎_𝑅 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.
