Possible candidates for the simultaneous breaking of multiple symmetries in odd-mass Kr, Br, and Rb isotopes

The deformations and the corresponding configurations of the odd-mass Kr, Br, and Rb isotopes are investigated using the adiabatic and configuration-fixed constrained triaxial relativistic mean field theory. Several minima with prominent triaxial deformation and proper configuration are obtained in [Formula: see text]Kr, [Formula: see text]Br, and [Formula: see text]Rb nuclei, indicating the existence of chiral doublet bands. Based on the discussions about the involved orbitals in the chiral configurations, the possible coexistence of chiral and reflection based on the pseudospin orbitals in the [Formula: see text]Kr, [Formula: see text]Br, and [Formula: see text]Rb nuclei has been suggested.
