Abstract
Angular distributions of neutrons from the reaction have been measured at 4.1-MeV bombarding energy for all bound levels in except the ground state. The 6.39-6.41-MeV doublet was not resolved. The angular distributions, generally, agree in relative magnitude and shape with those from analog states in the mirror reaction . This result is most easily understood by assuming that both reactions proceed predominately by compound-nucleus formation. The 8.43-MeV level in is observed to decay by emission even though it is unbound to -particle emission by 890 keV. This retardation of the decay cannot be understood as being due to the Coulomb barrier alone.
