Fully microscopic model analysis of the elastic and inelastic scattering of protons from C12 and for energies in the range 200 to 800 MeV

Medium modified effective two nucleon interactions are defined for protons incident upon C12 with energies in the range 200 to 800 MeV. Those effective interactions have been folded with the ground-state density to specify nonlocal optical potentials that were then used to analyze the elastic scattering differential cross sections and analyzing powers. A select set of isoscalar and isovector, positive and negative parity, inelastic proton scattering transitions have also been analyzed using the same (microscopic) optical models to define the distorted wave functions needed in distorted wave approximation (DWA) calculations of the associated differential cross sections and analyzing powers. All results are compared with ones found using the Love-Franey effective interactions. The nuclear structure relating to these transitions was chosen from (0+2)Latin small letter h with stroke and (1+3)Latin small letter h with stroke shell model calculations of the positive and negative parity spectra of C12, respectively. In comparison to previous DWA analyses, very good fits to most data over a range of energies are achieved with no variation being made to any of the input details, save for the choice of the effective interaction. Evidence of limitations of the spectroscopy and of specifics in the defined effective interactions at higher energies is found.
