STUDY OF PROTON-NUCLEUS TOTAL REACTION CROSS SECTION AT 30 ≤ EP ≤ 2200 MeV USING RELATIVISTIC MEAN FIELD DENSITIES

Within the optical limit approximation of Glauber multiple scattering model, the total reaction cross section is calculated for proton scattering on some stable and unstable nuclei, 6 ≤ A ≤17 at 30 ≤ EP ≤ 2200 MeV. The densities of the target nuclei are described by both relativistic mean field (RMF) approach and field motivated effective Lagrangian (E-RMF). We found that the values of σR are strongly correlated to the values of slope parameter of nucleon-nucleon (NN) scattering amplitude. In this study, for p –6Li and p-8B , the values of σR using E-RMF exceeded those calculated with RMF by about 3-6 % at Ep 100 MeV and 2-3 % at higher energies, while it was 1-2 % for p-9Be at all energy range. Introducing Coulomb correction provides results close to the experimental data at Ep 100 MeV. In general, the application of optical limit approximation succeeded in describing σR in the entire range of energy, with suitable values for slope parameter of NN scattering amplitude.
