研究了169Re的高自旋态能级结构,建立了组态为π9/2-[514]的强耦合带和组态为π1/2-[541]的退耦合带. 推转壳模型(Cranked shell model)计算结果表明组态相关的不同形变能够解释这些转动带的不同带交叉频率. 在已知的奇ARe核中,169Re的9/2-[514]转动带在低自旋时具有最大的能量旋称劈裂. 当一对i13/2中子顺排后,旋称劈裂发生了反转,并且劈裂的幅度非常显著地减少了. 另外,还观测到了一个三准粒子激发带,并指定了它的最可能组态为π9/2-[514](○X)νAE.

High-spin states in 169 Re were studied and resulted in the identification of a strongly coupled band based on the 9/2-[514] Nilsson state and a decoupled band built on the h9/2 intruder proton orbital (nominally 1/2-[541]). The cranked shell nodel calculations present configuration-dependent deformations that can explain the different band crossing frequencies. The experimental 9/2-[514] band in 169 Re shows the largest signature splitting at low spin among the known odd mass Re isotopes. After the alignment of a pair of the i13/2 neutrons, the phase of the splitting is inverted with a significantly reduced amplitude. Additionally, a three-quasipariticle band was observed and assigned to be built likely on the π9/2-[514](○X) AE configuration.
