Description of Chiral Doublets in $A\sim 130$ Nuclei and the Possible Chiral Doublets in $A\sim 100$ Nuclei

Abstract

The chiral doublets for nuclei in $A\sim 100$ and $A\sim 130$ regions have been studied with the particle-rotor model. The experimental spectra of chiral partners bands for four N=75 isotones in $A\sim 130$ region have been well reproduced by the calculation with the configuration $\pi h_{11/2}\otimes \nu h_{11/2}^{-1}$. The possible chiral doublets in $A\sim 100$ region have been predicted by the PRM model with the configuration $\pi g_{9/2}\otimes \nu g_{9/2}^{-1}$ based on the analysis of the spectra, the $\omega$-I relation, the $B(M1)$ and $B(E2)$ transition probabilities, and the structure of the wave functions. The possible chiral doublets for nuclei with asymmetric particle and hole configuration are also discussed.
