Abstract

The static quadrupole moments (SQMs) of multiple chiral doublet bands are investigated. An interesting finding for the SQM is the occurrence of a kink at specific spin values for various $γ$ values. The kink represents the transition point from planar to chiral rotation. This observation highlights a robust feature that the presence of a kink in the SQM plot serves as compelling evidence for the initiation of aplanar rotation. Thus, the SQMs presents a novel criterion for effectively distinguishing different modes of nuclear chirality.
