Abstract

• Reaction cross section of carbon isotopes for proton scattering is computed with the wide incident energy region. Calculations are based on eikonal approximation which is a high energy (small scattering angle) that depends on the nucleon nucleus (NA) optical potential. The proton-carbon optical potential is obtained by a folding integral of the nucleon nucleon (NN) transition amplitude and matter density of carbon. Analytical formulas of optical potential are used to present in position-space representation for carbon isotope by using harmonic well nuclear densities(A<20). The eikonal phase function is presented in the momentum-space representation which is obtained from computing the fourier transform of the position-space optical potential in order to compare each other.
