| Abstract: | High spin states of117Xe have been investigated by means of in-beam γ-ray spectroscopy using the reaction92Mo(28Si, 2pn) at beam energies of 100 to 120 MeV. The previously known νh11/2 bands are confirmed and the νg7/2 favored-signature band is extended up to 47/2+, in which two band crossings are observed at ?ω=0.33 and 0.44 MeV, respectively. Two new positive-parity bands have been established, one of which is most likely the νg7/2 unfavored-signature band. A new transition cascade with irregular level spacings is also observed. |
