High-spin states in {sup 122}Cs have been studied via the {sup 112}Sn({sup 12}C,{ital pn}) reaction. Two {Delta}{ital I}=1 band structures, along with {ital E}2 crossover transitions, are observed. One band is believed to be based on the {pi}{ital h}{sub 11/2}{direct product}{nu}{ital g}{sub 7/2} configuration. A band crossing is observed at a rotational frequency of {h bar}{omega}{sub {ital c}}=0.46 MeV which is expected from the alignment of an {ital h}{sub 11/2} neutron pair. The second band, believed to be based on the {pi}{ital g}{sub 7/2}{direct product}{nu}{ital h}{sub 11/2} 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.
