Abstract
The reactions and have been studied at 17 and 18 MeV, respectively. Both reactions are selective in the states they populate, although this is more evident in the (, ) case. Angular distributions were extracted for 15 levels below 8.5-MeV excitation. These exhibit pronounced structures and are generally indicative of direct-reaction mechanisms. Transitions to the negative-parity states at 3.06, 3.85, and 4.55 MeV are the strongest observed below 7-MeV excitation. These levels are discussed within the framework of the weak-coupling model and the transitions compared with those from the and reactions leading to the first rotational band in . Strong transitions are also observed to levels at 7.38, (8.46, 8.49), (8.87, 8.95), and (9.14, 9.20) MeV.
