Abstract
The reaction was studied using particle-gamma coincidence techniques and the 22-MeV alpha-particle beam of the Indiana University cyclotron. The 7.57-MeV level of is observed to decay by gamma emission to either the 5.28- or 5.30-MeV level. An upper limit of 10% is placed on the intensity of the ground-state branch. This information, together with the results of other experiments, suggests a spin and parity assignment of or for the 7.57-MeV level, which is consistent with shell-model predictions.
