Excited states in [Formula Presented] have been studied using the [Formula Presented] evaporation channel from the [Formula Presented] reaction at a beam energy of 250 MeV. A thin-target experiment was carried out using GAMMASPHERE coupled with the MICROBALL charged-particle detector array and an array of neutron detectors. A complementary thick-target experiment was performed with the Stony Brook six-Ge-detector array in order to measure the lifetime of an [Formula Presented] isomer observed in the GAMMASPHERE data. The structure of [Formula Presented] at low spin is dominated by the yrast [Formula Presented] band, although a band assigned to the [Formula Presented] configuration is also observed. Four collective bands have been found at higher spins. Experimental results are compared to the odd-[Formula Presented] Te systematics and to core-quasiparticle and total Routhian surface calculations.
