Abstract

High-spin states in $^{120}$ Te were populated in the reaction $^{80}$ Se( $^{48}$ Ca, $α 4 n$ ) $^{120}$ Te at a beam energy of 207 MeV and $γ$ -ray coincidences were measured using the Gammasphere spectrometer. The previously known level scheme is extended to higher spin and new interband transitions and side-feeding branches are established. Five highly deformed rotational bands, extending up to almost $I = 50$ , are observed for the first time. The bands are compared with similar structures found recently in neighboring nuclei. The experimental results are interpreted within the framework of the cranked Nilsson-Strutinsky model. Configuration assignments to several terminating states and to the high-spin bands are discussed.
