Abstract

Angular distributions for the elastic and inelastic scattering of 0.8 GeV protons from Ne20 and Ne22 are presented. Cross sections for protons exciting states up to about 14 MeV were measured using a high resolution spectrometer. Coupled-channels analyses of scattering cross sections for the 0+, 2+, 4+, and 6+ states in the ground-state rotational band, possible 2-, 3-, and 5- members of a K=2- octupole band, and possible 1-, 3-, and 5- members of a K=0- octupole band in Ne20 were performed. Also reported are coupled-channels analyses of the experimental angular distributions in Ne22 for the 0+, 2+, and 4+ states in the ground-state band, the K=2+ -vibrational band members, and the 2- and 3- members of a K=2- octupole band. Deformation parameters for states not in the ground-state rotational bands are obtained from a distorted-wave Born approximation analysis of these data. Multipole moments inferred from the deformed optical potentials are compared with moments obtained with electromagnetic measurements, low-energy proton, deuteron, He3, and He4 scattering, and shell-model calculations.
