Description of chiral doublets inA∼130nuclei and the possible chiral doublets inA∼100nuclei

The chiral doublets for nuclei in $A\sim 100$ and $130$ regions have been studied with the particle-rotor model. The experimental spectra of chiral partner 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 particle-rotor 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 $B\left(M1\right)$ and $B\left(E2\right)$ transition probabilities, and the structure of the wave functions. The possible chiral doublets for nuclei with asymmetric particle and hole configurations are also discussed.
