Chiral geometry of higher excited bands in triaxial nuclei with particle-hole configuration

Abstract

The lowest six rotational bands have been studied in the particle-rotor model with the particle-hole configuration $\pi h_{11/2}^1\otimes \nu h_{11/2}^{-1}$ and different triaxiality parameter $\gamma$. Both constant and spin-dependent variable moments of inertial (CMI and VMI) are introduced. The energy spectra, electromagnetic transition probabilities, angular momentum components and $K$-distribution have been examined. It is shown that, besides the band 1 and band 2, the predicted band 3 and band 4 in the calculations of both CMI and VMI for atomic nuclei with $\gamma =30^{\circ }$ could be interpreted as chiral doublet bands.
