Abstract
-ray decay of the 2.15- and 3.59-MeV levels was studied following population via the reaction at MeV. The rays were detected in coincidence with particles observed in an axially symmetric silicon detector centered at 180° to the beam. -ray branching ratios were extracted for both levels. From the angular distributions of the decay rays, results were obtained for the mixing ratios of the decay of the 3.59-MeV level to the ground state, the 0.72-MeV level, and the 2.15-MeV level, respectively, as follows: , , , all pertaining to transitions. For the decay of the 2.15-MeV level to the 0.72-MeV level, . Combining these results with previous work gives information on the magnitudes as well as the relative phases of the and matrix elements considered. These results are compared with the predictions of the independent-particle model.
