Abstract

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 p³ He have also been achieved. For p⁴ He, the calculated reaction cross-section becomes negative at lower energies which is absolutely unphysical.
