Staggering of the B(M1) value as a fingerprint of specific chiral bands structure

TL;DR

This paper investigates how the staggering of the B(M1) value can serve as a unique fingerprint for identifying specific chiral bands in nuclei, revealing that gamma selection rules are influenced by structural factors beyond chiral symmetry breaking.

Contribution

It demonstrates that gamma selection rules in nuclear chiral bands depend on structural composition, including particle configuration and core deformation, not solely on chiral symmetry breaking.

Findings

B(M1) staggering correlates with chiral band structure.

Gamma selection rules are influenced by particle configuration and deformation.

Chiral symmetry breaking alone does not explain selection rules.

Abstract

Nuclear chirality has been intensively studdied for the last several years in the context of experimental as well as theoretical approach. Characteristic gamma selection rules have been predicted for the strong chiral symmetry breaking limit that has been observed in Cs isotopes. The presented analysis shows that the gamma selection rules cannot be attributed only to chiral symmetry breaking. The selection rules relate to structural composition of the chiral rotational bands, i.e. to odd particle configuration and the deformation of the core.
