Abstract
The angular distribution of particles produced by the reaction and leading to the ground state of the residual nucleus has been measured at six resonances occurring in the region Mev. The measured distributions are compared to the calculated angular distributions. In many cases the calculated angular distribution for a given type of compound state is not unique in that an unknown mixture of channel spins enters as well as possible admixtures of higher values. The best assignments for the resonances at 1.137, 1.012, and 1.166 Mev are respectively , , and . A large anisotropy is observed for the resonance at 1.288 Mev which is not predicted by any simple assignment. It can, however, be fitted by a assignment in which there is a rather large admixture of -wave to the -wave protons. The resonance at 1.804 Mev is found to be complex.
