Elastic scattering analysis of p+40 Ca at incident energies from threshold to 48.4 MeV and nuclear matter radius

Proton elastic scattering at various incident energies is one method to study nuclear density distributions and nuclear radii. Single folding potential describing the p-scattering on 40Ca over a broad energy range 9-48.4 MeV is constructed. The resulting potential does not need any renormalization to fit the measured elastic scattering angular distributions and total reaction cross-sections. Furthermore, correlation between volume integral and proton incident energy is discussed. Theoretical calculations are in a good agreement with existing experimental data. © 2015 World Scientific Publishing Company.
