Rotational features of vibrator nucleus 118Te -: art. no. 014312

High-spin states in Te-118 have been populated via heavy-ion induced reactions. Excited states were observed up to I = 32 (h) over bar and, in addition to irregular level sequences, several bands were identified for the first time. The decoupled negative parity bands based upon 7(-) and 8(-) states are interpreted to arise from the proton h (11/2)g(7/2) configuration coupled to the 2p-2h intruder states in Sn-116. These bands show very smooth alignment behavior, in accordance with the proton h(11/2) bands in neighboring Sb and I nuclei. Above I = 20 the yrast positive parity band is built on the proton h(11/2)(2) configuration, also coupled to the proton 2p-2h excitation. The strongly coupled band built upon the 2914 keV 6(+) state involves a proton hole on the g(9/2) orbital. Another strongly coupled band based upon the 5006 keV I = 11 (h) over bar state was also observed.
