Abstract

Lifetimes of low-lying excited states have been measured in Ge-66, Se-69, and Ga-65 using a gamma-ray lineshape method. The results confirm the previously reported 7(1)(-) state lifetime in Ge-66. The lifetime of the yrast 5/2(-) state in Ga-65 is measured for the first time. Lifetime measurements of two excited 3/2(-) states in Se-69 are also reported. Two previously unobserved. rays have been identified in Se-69. gamma - gamma coincidence measurements have been used to place one of these in the level scheme gamma Se-69 excited state populations are compared to shell-model calculations using the GXPF1A interaction in the fp model space. Theoretical spectroscopic factors to excited states in Se-69 have identified three candidate levels for the origin of one of the new transitions.
