The recently observed two and four-quasiparticle high-spin rotational bands in the odd-odd nuclei ^{166,168,170,172}Re are investigated using the cranked shell model with pairing correlations treated by a particle-number conserving method. The experimental moments of inertia and alignments can be reproduced well by the present calculation if appropriate bandhead spins and configurations are assigned for these bands, which in turn confirms their spin and configuration assignments. It is found that the bandhead spins of those two rotational bands observed in ¹⁶⁶Re (Li et al., 2015) [8] should be both increased by 2ħ to get in consistent with the systematics of the experimental and calculated moments of inertia for the same configurations in ^168,170,172Re. The variations of the backbendings/upbendings with increasing neutron number in these nuclei are investigated. The level crossing mechanism is well understood by analyzing the variations of the occupation probabilities of the single-particle states close to the Fermi surface and their contributions to the angular momentum alignment with rotational frequency. In addition, the influence of the deformation driving effects of the proton $1/2^{-}[541]$ ($h_{9/2}$) orbital on the level crossing in ¹⁷²Re is also discussed.

使用曲柄壳模型研究了最近观察到的奇偶核^{166,168,170,172} Re 中的两个和四个准粒子高自旋旋转带，该模型具有通过粒子数守恒方法处理的配对相关性。如果为这些带分配了适当的带头旋转和配置，则可以通过本计算很好地再现实验惯性矩和对齐，这反过来确认了它们的旋转和配置分配。发现在¹⁶⁶ Re (Li et al., 2015) [8] 中观察到的这两个旋转带的带头自旋应该都增加 2 ħ以与实验和计算惯性矩的系统学一致相同的配置^168,170,172回复。研究了随着这些核中中子数的增加，后弯/上弯的变化。通过分析靠近费米面的单粒子态占据概率的变化及其对角动量与旋转频率对齐的贡献，可以很好地理解水平交叉机制。此外，质子变形驱动效应的影响$1/2^{-}[541]$ ($H_{9/2}$) 轨道在¹⁷² Re的平交道口上也进行了讨论。
