Intruder bands inTe114: Smooth band termination

The nucleus ${}_{}{}^{114}{}_{}{}^{}\mathrm{Te}$ has been studied in heavy-ion γ-ray spectroscopy experiments performed with the early implementation of the GAMMASPHERE multidetector array. Three rotational intruder bands have been observed up to high spins. The yrast band, involving the 4p2h (${\mathit{h}}_{11/2}$ ${)}^2$(${\mathit{g}}_{7/2}$ ${)}^2$(${\mathit{g}}_{9/2}$ ${)}^{\mathrm{-}2}$ proton configuration, reaches I=48ħ at an excitation energy of 30.3 MeV, the highest observed spin connected by γ rays in this mass region. The band properties are interpreted in the framework of smooth band termination.
