Abstract

High-spin states in Cs122 have been studied via the Sn112(12C,pn) reaction. Two I=1 band structures, along with E2 crossover transitions, are observed. One band is believed to be based on the h11/2g7/2 configuration. A band crossing is observed at a rotational frequency of Latin small letter h with strokec=0.46 MeV which is expected from the alignment of an h11/2 neutron pair. The second band, believed to be based on the g7/2h11/2 configuration, is observed up to high spin. The two signatures of this negative parity band show a small signature splitting as well as a common upbend. Calculations with both the cranked shell model (CSM) and a geometrical model are utilized to define the configurations and quasiparticles corresponding to the band crossings in this nucleus.
