Description
The levels in 127Xe have been studied with the 126Te(3He,2n) and 128Te(3He,4n) reactions and in 129Xe with the 130Te(3He,4n) and 126Te(α,n) reactions using enriched Te targets and in-beam γ-ray and conversion-electron spectroscopic methods. In addition to the hsub(11/2) level structures, positive-parity bands based on different low-j states were observed in both nuclei. The observed gsub(7/2) band head at 342.2 keV in 127Xe is an isomeric state with a half-life of 37+-3 ns. Both triaxial-rotor and core-plus-quasiparticle model calculations have been carried out to explain the observed band structures in 123-129Xe. The calculations indicate different shapes for the positive- and negative-parity level system. (author)
