Abstract
High-spin states in 124,125,126Xe have been populated in the reaction 82Se (48Ca, xn)130−xXe and -ray coincidences were measured with the GAMMASPHERE spectrometer. Twelve new bands extending into the spin 50–60 ~ region are identified in 125Xe and 126Xe and previously known rotational bands at low spins are confirmed and extended. Earlier known structures in 124Xe are confirmed and a new band is observed. Irregular structures are identified at the top of the yrast and a side band in this nucleus. Configuration assignments for the different structures are suggested.
