An analytical description of the parity-doublet structure in an odd-A nucleus

Journal article, 2021

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 Pm151, and there is a good agreement with calculated and experimental results.
