Levels excited up to 39.8 MeV and 119/2 units of angular momentum have been populated in {sup 125}Xe by the {sup 82}Se({sup 48}Ca,5n){sup 125}Xe 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 60 ({h_bar}/2{pi}) 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 31-55 ({h_bar}/2{pi}) and were found to be in agreement with the CSM calculations. The corresponding quadrupole deformation {epsilon}{sub 2} ranges from 0.28 to 0.34 at a {gamma} deformation of 0 deg. and from 0.29 to 0.36 at a {gamma} value of 5 deg.
