| 摘 要： | 利用重离子融合蒸发反应159Tb（29Si，4nγ）194Au布居了形变双奇核184Au的高自旋态，用GASP探测器阵列进行了在束γ实验测量．通过对实验数据的深入分析，新发现了一条可归属于184Au核的强耦合转动带．基于对转动带有效K值的分析以及从实验数据中提取出的带内B（M1）／B（E2）值与理论计算值的比较，建议了转动带的准粒子组态和能级的自旋宇称值．

| Abstract: | High-spin states in deformed odd-odd 184Au have been investigated using the 159TbC9Si, 4nT）184Au fusionevaporation reaction and the multidetector array of GASP. Through detailed analysis of γ-γ coincidence relationships, a new strongly coupled band has been identified and assigned to 184Au. According to the effective projection quantum number Keff and the deduced in-band B（M1）/B（E2） ratios, the quasiparticle configuration and spin and parity have been proposed to the newly observed band, |
