Abstract
22 levels of below MeV are populated by the -ray decay of the three resonances at keV in the reaction . These resonances, selected for study because of their dominant modes of decay to levels above 2.7 MeV for which limited prior data exist, were investigated with an 80- Ge(Li) detector, and with Ge(Li)-NaI coincidence and angular-correlation techniques. The results obtained for levels below 2.3 MeV are in general agreement with other recent work. A new result is a probable assignment for the 2.180-MeV level. For higher-lying levels, -ray decay schemes and excitation energies with errors in the range from ±0.3 to ±2.3 keV were determined for 14 bound states in the range MeV and the three resonance levels. The reaction value was determined with the result keV. The following assignments (energies in MeV) result from the combination of the present work with a recent study: 2.72, ; 3.55, ; 3.60, ; 3.63, ; 3.77, ; 3.98, ; 4.08, ; 4.14, 2; 4.35, probably ; 4.42, 1, 2, or 3; 4.51, probably ; and 4.64, 2, 1, or 3. The resonance level assignments are , , and . It is shown that the three resonances are probably each odd-parity levels. The probable shell-model configurations of some of the odd-parity levels are discussed.
