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

Differential cross sections and analyzing powers for elastic proton scattering from, and for inelastic proton scattering to a set of View the MathML source 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, View the MathML source), 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.
