本文讨论了用旋转变形核中独立粒子运动解释高自旋离散线数据的最新进展。特别注意的是从对应于多准中子配置的Routhians和那些从“实验”值的构成单准中子配置的构造的比较得到的剩余相互作用的解释。类似地，在奇N核中对应于i 13/2对中子的排列的带交叉频率与价准中子轨道的形状之间的相关性被建立用于各种配置。剩余的相互作用和带交叉频率之间的对应关系进行了讨论，并提取估计的配对减少与“阻塞”的一个单一的准中子与BCS估计恒定的水平间距进行比较。最后，对180 Os中h9/2质子排列频率在vn = 2，π = +和vn = 4，π =-带之间移动的物理基础提出了一些建议。
Recent developments in the interpretation of high-spin, discrete-line data in terms of independent-particle motion in a rotating deformed nucleus are discussed. Particular attention is given to the interpretation of the residual interactions derived from a comparison of routhians corresponding to multiple-quasineutron configurations and those constructed from "experimental" values of the constituent single-quasineutron configurations. Similarly, the correlation between band-crossing frequencies in odd-N nuclei corresponding to the alignment of an i13/2 pair of neutrons, and the shape of the valence quasineutron orbit is established for a variety of configurations. The correspondence between the residual-interactions and band-crossing frequencies is discussed, and the extracted estimate of the pairing reduction associated with the "blocking" of a single quasineutron is compared with BCS estimates for constant level spacings. Finally, some suggestions are made concerning the physical basis of the shift in the h9/2 proton alignment frequencies between vn = 2, π = + and vn = 4, π = − bands in 180Os.
