Rotational features of vibrator nucleus118Te

subject

description

High-spin states in ${}^{118}\mathrm{Te}$ have been populated via heavy-ion induced reactions. Excited states were observed up to $I=32\ensuremath{\Elzxh}$ and, in addition to irregular level sequences, several bands were identified for the first time. The decoupled negative parity bands based upon ${7}^{\ensuremath{-}}$ and ${8}^{\ensuremath{-}}$ states are interpreted to arise from the proton ${h}_{11/2}{g}_{7/2}$ configuration coupled to the $2p\ensuremath{-}2h$ intruder states in ${}^{116}\mathrm{Sn}.$ 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 $2p\ensuremath{-}2h$ 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 $I=11\ensuremath{\Elzxh}$ state was also observed.
