Abstract
Levels excited up to 39.8 MeV and 119/2 units of angular momentum have been populated in Xe-125 by the Se-82(Ca-48,5n)Xe-125 reaction. High-fold gamma-ray coincidence events were measured using the Gammasphere Ge detector array. Nine regular rotational bands extending from levels identified previously up to almost 60h have been identified, and three of these have been connected to low-lying levels having well-established spins and parities. Configurations have been assigned to six of the bands based on alignment properties, band crossings, and comparison with theoretical cranked shell model calculations (CSM). Transition quadrupole moments have been measured for these bands in the spin range 31-55h and were found to be in agreement with the CSM calculations. The corresponding quadrupole deformation c(2) ranges from 0.28 to 0.34 at a gamma deformation of 0 degrees and from 0.29 to 0.36 at a gamma value of 5 degrees.
