Abstract

Excited states in ¹¹¹Te have been studied using the 4pn evaporation channel from the ⁵⁸Ni+⁵⁸Ni 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 11/2^- isomer observed in the GAMMASPHERE data. The structure of ¹¹¹Te at low spin is dominated by the yrast vh_11/2 band, although a band assigned to the v(g_7/2d_5/2) configuration is also observed. Four collective bands have been found at higher spins. Experimental results are compared to the odd-A Te systematics and to core-quasiparticle and total Routhian surface calculations.
