Abstract
The decays of the two lowest states in at 8.97 and 9.22 MeV were studied as resonances in the reaction by use of a gas cell and a 30-cc Ge(Li) detector. For the lower resonance, we find three branches: to the ground state (11%), to the first excited state (50%), and to the second excited state (39%). These results imply that for the state. On the simple rotational model, transitions from states of the (Nilsson orbit #6) band are possible only to the ground-state (#7) band. A , assignment for the lowest state fits the observed branching ratios. The second resonance decays predominantly to the ground state, and there is at most a 9% branch to the state at 2.41 MeV. The second resonance is assigned , . If the 2.41-MeV state is (#9), no transition to it is expected. On both resonances, transitions to higher excited states are obscured by background.
