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.

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.

T Values

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.

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.

We obtain Thomas–Fermi solutions for nuclei in the mass range [Formula: see text]. Solutions for a given nucleus are obtained from angular momentum zero to the maximum value at which the nucleus breaks up. On one hand, we can establish contact with the liquid-drop model; on the other hand since Thomas–Fermi theory can be regarded as an approximation to Hartree-Fock theory and does use an underlying force (the same force can be used in Hartree–Fock theory), it is also instructive to compare results with the quantum cranking calculations carried out by other researchers. It appears that for low-mass nuclei quantum effects make the two results very different even at high spins but for medium-mass nuclei there are similarities that are seen at high-spin states. Rather large deformations are obtained at high-spin states but the magnitudes are sensitive to the actual force used. We present graphs indicating the change of shape in the Q – γ plane as angular momentum is cranked up.
