Abstract
Electromagnetic transition widths, reduced widths, and inelastic scattering cross sections are calculated for the following states of and : (1) The levels arising from the ground-state configuration, , (2) the odd-parity levels arising from excitation of a nucleon into the degenerate and shells, (3) the even-parity group of levels formed by excitation of two nucleons into the and shells. The calculations for the configuration are carried out using the wave functions of Elliott and of Visscher and Ferrell, and in coupling. The calculations for the odd-parity levels are done in the -coupling scheme. For the even-parity excited configuration an inert core is assumed and radiative widths are calculated for states arising from . The calculations are compared to the existing data. On the basis of this comparison shell-model assignments are proposed for 19 of the 27 known levels below 11-Mev excitation in and for all the known levels in below 9-Mev excitation.
