Relativistic impulse approach for proton elastic scattering with 58Ni and 120Sn at Ep=200, 300 and 400 MeV Original Research Article

We calculate proton elastic scattering with 58Ni and 120Sn at various intermediate energies with relativistic impulse approximation (RIA). We use the ground-state wave functions of the relativistic mean-field (RMF) calculation with the use of the TMA parameter set. We found good agreement with experimental data for the elastic scattering observables. In addition to the standard scalar and vector densities, we include also the tensor density. We study the Pauli effect and the vacuum polarization effect on the elastic scattering observables using the prescription of Horowitz and Serot at lower energy.
