Angular distributions for the elastic and inelastic scattering of 0.8 GeV protons from /sup 20/Ne and /sup 22/Ne 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/sup +/, 2/sup +/, 4/sup +/, and 6/sup +/ states in the ground-state rotational band, possible 2/sup -/, 3/sup -/, and 5/sup -/ members of a K/sup ..pi../ = 2/sup -/ octupole band, and possible 1/sup -/, 3/sup -/, and 5/sup -/ members of a K/sup ..pi../ = 0/sup -/ octupole band in /sup 20/Ne were performed. Also reported are coupled-channels analyses of the experimental angular distributions in /sup 22/Ne for the 0/sup +/, 2/sup +/, and 4/sup +/ states in the ground-state band, the K/sup ..pi../ = 2/sup +/ ..gamma..-vibrational band members, and the 2/sup -/ and 3/sup -/ members of a K/sup ..pi../ = 2/sup -/ 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, /sup 3/He, and /sup 4/He scattering, and shell-model calculations.
