Possible wobbling motion in multiple chiral doublets

The analysis of mixing ratios delta the Delta I = 1 linking transitions in the chiral and multiple chiral doublet bands with the ideal case are theoretically performed for the first time by employing the quantum particle rotor model. The calculated E2 fraction extracted from the mixing ratio show that the Delta I = 1 linking transitions in the lowest and excited chiral doublet bands are of the pure M1 character, while those connecting the excited to lowest chiral doublet bands are of M1/E2 character with a relatively large E2 admixture. The further analysis of the angular momentum geometry and azimuthal plots reveals that the excited chiral doublet bands represents a chiral geometry with a wobbling motion of the core. This provides a possible figure of wobbling motion in multiple chiral doublets. (C) 2022 The Author(s). Published by Elsevier B.V.

Automated summary

In this study, the mixing ratios of Delta the Delta I = 1 linking transitions in the chiral and multiple chiral doublet bands were analyzed for the first time using the quantum particle rotor model. The calculated results showed that the Delta I = 1 linking transitions in the lowest and excited chiral doublet bands were of pure M1 character, while those connecting the excited to lowest chiral doublet bands had an M1/E2 character with a relatively large E2 admixture. Further analysis of the angular momentum geometry and azimuthal plots revealed that the excited chiral doublet bands represented a chiral geometry with a wobbling motion of the core, providing a possible figure of wobbling motion in multiple chiral doublets.
