Microscopic model analyses of elastic proton-C-12 scattering with energies40 to 800 MeV - art. no. 024605

Medium modified effective two nucleon interactions have been defined for pr otons incident upon C-12 With energies ranging from 40 to 800 MeV. Those ef fective interactions have been folded with ground state density matrices fr om a large space shell model of C-12 to give complex nonlocal optical poten tials. With these the elastic scattering differential cross sections and an alyzing powers have been analyzed. Good results are obtained when the effec tive interactions are linked to NN interactions that fit NN scattering data and when exchange amplitudes in scattering that lead to strong nonlocality in the optical potentials are taken into account.
