论文摘要

为了使对变形的稀土区域或变形核中的旋转带的一般了解,在$^{167} $ lu中观察到的正常成型的旋转结构在未配对和配对的Nilsson-Strutinsky STRUTINSKYSKYSKYSKYSKYSURISMS,CNS,CNS和CNSB中被解释。特别关注的是乐队交叉点。对于$ H_ {11/2} $ shell中的Fermi表面的该核,我们得出的结论是,除了配置配对的配置中,分别均匀且奇数的$ i_ {13/2} $中子,在未划分的形式上可以理解观察到的频段交叉。特别是,这意味着在AB和BC交叉口上方,带自旋的演变被描述为闭合壳外壳外颗粒的自旋向量的逐渐比对。因此,配置的特征是占据开放的$ j $ shells或$ j $ shells的颗粒数。在本研究中,我们修改了某些实验带的解释以及交叉的性质,同时确认了一些以前的配置分配。

With the aim to get a general understanding of rotational bands in the deformed rare-earth region or in deformed nuclei in general, the observed normal-deformed rotational structures in $^{167}$Lu are interpreted within the unpaired and paired cranked Nilsson-Strutinsky formalisms, CNS and CNSB. Particular attention is devoted to the band crossings. For this nucleus with the Fermi surface high up in the $h_{11/2}$ shell, we conclude that except for the paired AB and BC crossings in configurations with an even and odd number of $i_{13/2}$ neutrons, respectively, the observed band crossings can be understood within the unpaired formalism. Especially, it means that above the AB and BC crossings, the evolution with spin is described as a gradual alignment of the spin vectors of the particles outside closed shells. Consequently, the configurations can be characterized by the number of particles occupying open $j$-shells or groups of $j$-shells. In the present study, we revise the interpretation of some experimental bands and also the nature of the crossings while some previous configuration assignments are confirmed.
