Abstract
Measurements of the radiative decay of the triplet of levels at 1.346, 1.459, and 1.554 MeV in have been made with a Ge(Li) -ray spectrometer. Results of lifetime measurements for these states when averaged with previous work are, respectively, psec, 0.084±0.020 psec, and fsec. Accurate energies of the three states were determined to be 1345.75±0.20, 1459.1±0.5, and 1554.1±0.3 keV. Information on decay modes and mixing ratios has also been obtained for these states. The decay branching of the 1.459-MeV level was found to differ significantly from that reported by previous investigators. The results are compared with various model predictions.
