摘要：

The level structure of 125Xe has been studied with the(3He, 3nγ) reaction on an enriched 125Te target using in-beam γ-ray spectroscopic methods. In addition to the negative-parity level structure, an extensive previously unknown positive-parity band structure based on different low-j states was observed. The odd-parity h 11 2 level system is well reproduced with the triaxial rotor model. However, the positive-parity band structure is qualitatively interpreted with a particle-plus-vibrating-core model. The observed g 7 2 band head at 295.9 keV is an isomeric state with a half-life of 140 ± 30 ns. © 1979.
