Abstract
The positive-parity doublet bands with configuration $\ensuremath{\pi}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}{h}_{11/2}$ and negative-parity bands with $\ensuremath{\pi}{h}_{11/2}\ensuremath{\bigotimes}\ensuremath{\nu}({g}_{7/2}{d}_{5/2})$ observed in $^{124}\mathrm{Cs}$, and the possibility of multiple chiral doublets ($\mathrm{M}\ensuremath{\chi}\mathrm{D}$) with octupole correlations are investigated using the reflection-asymmetric triaxial particle rotor model. The calculated excitation energies, energy staggering parameters, and the electromagnetic transitional probabilities are in good agreement with the data available and satisfy the expected features of chiral doublet bands. The angular momentum geometry and its evolution with spin are studied with the angular momentum components and the azimuthal plot. In comparison with a typical chiral vibration pattern for the positive-parity doublet bands, a transient static chirality around $I=12\ensuremath{\hbar}$ is shown for the calculated negative-parity doublet bands.
