Abstract

High-spin states in $^{122}$ Te were populated in the reaction $^{82}$ Se( $^{48}$ Ca, ${α 4 n)}^{122}$ Te at a beam energy of 200 MeV and $γ$ -ray coincidences were measured with the Gammasphere spectrometer. The previously known level scheme was extended to considerably higher spin. Maximally aligned states and several high-energy transitions feeding into some of these levels were observed. In addition, seven collective high-spin bands were discovered for the first time in this nucleus. The experimental results are compared with cranked Nilsson-Strutinsky model calculations and possible configuration assignments to the new high-spin structures are discussed.
