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

The lowest six rotational bands have been studied in the particle-rotor model with the particle-hole configuration πh11/21-νh11/2-1 and different values of the triaxiality parameter γ. Both constant and spin-dependent variable moments of inertia (CMI and VMI, respectively) are introduced. The energy spectra, electromagnetic transition probabilities, angular momentum components, and K distribution are examined. It is shown that, besides bands 1 and 2, the predicted bands 3 and 4 in the calculations with both CMI and VMI for atomic nuclei with γ=30⊃°could be interpreted as chiral doublet bands.
