Microscopic Study of Total Reaction Cross-sections for Proton on Deuteron, 3 He and 4 He at Energy Range 20 to 50 Mev

摘要

Working within the framework of Coulomb modified Galuber model and using harmonic oscillator shell model target density, the proton total reaction cross-sections on the deuteron, 3 He and 4 He have been analyzed in the beam energy range 20 to 50 MeV. A very satisfactory agreement with experimental data for p-deuteron and to some extent for p- 3 He have also been achieved. For p- 4 He, the calculated reaction cross-section becomes negative at lower energies which is absolutely unphysical.
