Abstract
14 deuteron groups populating levels to 10.26 MeV excitation in have been measured with the reaction. Excitation functions measured at from 20.0 to 21.2 MeV reveal little structure, and therefore probably little compound-nuclear contribution to the observed cross sections for the deuteron groups. In particular, the level at 4.97 MeV excitation, strongly populated at MeV, is weakly populated in the present energy range. The "-forbidden" level at 4.25 MeV excitation, on the other hand, is strongly populated in the present energy range. A collective-model coupled-channel Born-approximation analysis of angular distributions measured at MeV is better able to explain the data than distorted-wave Born-approximation analysis for the positive-parity states. The negative-parity states are poorly described by both theories.
