In this paper, we discuss an analytical description of a parity-doublet structure for an odd-A nucleus. We use the controlled single particle (CSP) concept to present the analytical model. In a parity-doublet structure, those bands consisting of states with opposite positive and negative parity appear. At first glance, it seems complex to present an analytical description, but the CSP concept enables us to present an analytical description of such an event. The calculated results are compared to the experimental data of ${}^{151}\text{Pm}$, and there is a good agreement with calculated and experimental results.

奇A原子核中奇偶双峰结构的解析描述

在本文中，我们讨论了奇A原子核的奇偶双峰结构的解析描述。我们使用受控单粒子（CSP）概念来介绍分析模型。在双偶校验结构中，出现由正负相反的状态组成的那些带。乍一看，提供分析描述似乎很复杂，但是CSP概念使我们能够提供此类事件的分析描述。将计算结果与的实验数据进行比较${}^{151}\text{下午}$，与计算结果和实验结果吻合良好。
