Abstract
In this work we study the effect of the Coulomb energy shift on proton
total reaction cross-section (σR) at
25, 50, and 100 MeV for several nuclei in the mass region
12≤A≤208. The cross-sections are computed using the
Coulomb modified Glauber model in the optical limit approximation, and
the semi-phenomenological proton and neutron density distributions. We
find that the Coulomb energy shift has a significant effect on the
calculated σR, and that it brings the
theory quite close to the experiment.
