Data from the excitation of the 13�35, 18�35, 19�20 and 19�40 MeV states in 12C by the inelastic scattering of protons have been analysed using a fully microscopic distorted wave approximation to determine optimal assignments from amongst the current and ambiguous J π; T values of each state involved. While not conclusive, the present analysis suggests the assignments of 4-1; 0, 2-2; 0, 4-2; 0 and 22-2; 1 respectively.

Distorted wave approximation analyses of the inelastic scattering of 49�5 MeV protons from 24Mg and 28Si are used to compare 2 + transition densities that were obtained from a standard shell model, deformed potential models and an SU(3) model of the low excitation spectroscopy of these nuclei. Analysing power predictions do not reproduce the data adequately, and the discrepancies indicate a deficiency in the prescription for the transition mechanism.

Inelastic Proton Scattering

Distorted wave approximation analyses of 135 MeV inelastic proton scattering to high spin (4 - and 6-) unnatural parity states in 24Mg and 28Si have been made to test the character of an effective two-nucleon interaction, assuming a transition spectroscopy of particle-hole excitation from a projected Hartree-Fock intrinsic ground state.

Inelastic Proton Scattering

An analytic distorted wave approximation (ADWA) has been developed for use in analyses of intermediate energy inelastic proton scattering from nuclei. Applications are made to analyse 402 and 800 MeV data from the isoscalar and isovector 1 + and 2+ states in 12C and to the 800 MeV data from the excitation of the 2-(8�88 MeV) state in 160. Comparisons of predictions made using different model two-nucleon t matrices and different models of nuclear structure are given.

The application of the interacting boson model to the coupled channel description of inelastic proton scattering is studied. The radial shape of the transition potentials is determined by analogy to the usual geometrical models, whereas the reduced matrix elements are calculated from the boson Hamiltonian. The general formalism is applied to scattering from the Ge isotopes. We find a better description for the heavier isotopes in terms of an O(6)-symmetric model than for a vibrational model.
