Abstract
The excitation energies and -ray decay modes of the low-lying states of have been studied using the reaction. Some lifetime limits were obtained by the Dopplershift-attenuation method. The lifetimes of the levels at 461 and 666 keV, and the (, 0) level at 1230 keV were measured to be 7.1 ± 0.7, 12.8 ± 1.0, and 19.4 ± 1.4 psec, respectively, using the recoil-distance (plunger) technique with the reaction. The transition strengths from these three levels are discussed qualitatively in terms of calculations involving simple configurations, and are compared with recent detailed shell-model calculations.
