标题： Analysis of Delta I =2 staggering in nuclear rotational spectra

摘要： 提出并检验了一种用于分析核转动带中观察到的 ΔI = 2 振荡的方法。我们研究了六个超变形和极大变形带，其中 149Gd 的带以及可能还有 147Gd 的带似乎表现出真正的振荡现象。然而，我们强调振荡的存在并不一定意味着分支的发生。还表明，在通常变形带中看到的类似振荡是带交叉的表现。计划进行更广泛的分析。 显示英文摘要

摘要： A method is proposed and tested for the analysis of Delta I=2 staggering observed in nuclear rotational bands. We examine six super- and hyper-deformed bands, among which that of 149Gd and possibly of 147Gd seem to exhibit real staggering. However, we emphasize that the presence of staggering may not necessarily imply the occurrence of bifurcation. It is also shown that a similar staggering seen in normally deformed bands is a manifestation of band crossings. A more extensive analysis is planned.
