Abstract

Excited states have been populated in 52110Te via the Ni58(Ni58,α2pγ) reaction at 250 MeV. The Gammasphere γ-ray spectrometer was augmented with ancillary detectors for charged-particle and neutron detection in order to provide clean channel selection. The known level scheme of Te110 has been greatly expanded with the addition of many new structures. Above spin 8+, negative-parity structures become yrast. The level scheme of Te110 below 30 is discussed in this paper, including possible evidence for octupole correlations inferred from strong B(E1) strengths.
