摘要：
先前为描述 $^{208}$Pb 中此类高自旋态而建立并应用的方法，被推广到具有更复杂多声子结构的态。该方法采用重正化声子下的谐振近似，其中声子本身是在基于无规相位近似（RPA）的非线性版本模型中确定的，该模型同时包含 RPA 关联和超越 RPA 的关联。平均场和剩余相互作用是在自洽 RPA 框架内从 Skyrme 型能量密度泛函导出的。该方法被应用于分析双幻核 $^{208}$Pb 和 $^{40}$Ca 以及半幻核 $^{90}$Zr 中可获得的实验数据。
英文摘要：
The method of description of the high-spin states, which was previously developed and applied for the states of this type in $^{208}$Pb, is generalized for the case of the states having more complex multiphonon structure. In this method, the harmonic approximation with the renormalized phonons is used in which the phonons themselves are determined within the non-linear version of the model based on the random-phase approximation (RPA) and including both the RPA correlations and the beyond-RPA ones. The mean field and the residual interaction are derived within the framework of the self-consistent RPA from the energy-density functional of the Skyrme type. The method is applied for the analysis of the available experimental data in doubly magic $^{208}$Pb and $^{40}$Ca and in semi-magic $^{90}$Zr.
