Microscopic model analyses of proton scattering from ¹²C, ²⁰Ne, ²⁴Mg, ²⁸Si and ⁴⁰Ca

Differential cross sections and analyzing powers for elastic proton scattering from, and for inelastic proton scattering to a set of 2₁⁺ states in, ¹²C, ²⁰Ne, ²⁴Mg, ²⁸Si and ⁴⁰Ca, and for a set of energies between 35 to 250 MeV, have been analyzed. A g-folding model has been used to determine optical potentials and a microscopic distorted wave approximation taken to analyze the inelastic data. The effective nucleon-nucleon interactions used to specify the optical potentials have also been used as the transition operators in the inelastic scattering processes. Shell and large space Hartree-Fock models of structure have been used to describe the nuclear states. The calculations are in general agreement with the data when the cross sections are in excess of ∼ 1 mb / sr (elastic) and ∼ 0.1 mb / sr (inelastic, 2₁⁺), which suggests that other small effects (such as coupled-channel diagrams) are necessary before agreement between theory and data can be found at large scattering angles. However, the agreement found otherwise gives credibility to the models of structure considered.
