# Chirality of $^{135}$Nd reexamined: Evidence for multiple chiral doublet bands

## TL;DR

This paper reports the discovery of multiple chiral doublet bands in the nucleus $^{135}$Nd, supported by theoretical calculations, marking a significant step in understanding nuclear chirality phenomena.

## Contribution

It provides the first evidence of multiple chiral doublet bands in $^{135}$Nd, expanding the known cases of M$ ext{ extperiodcentered}$D in the $A ext{ extperiodcentered}130$ region.

## Key findings

- Identification of a new pair of positive-parity chiral doublet bands.
- Confirmation of multiple chiral doublet bands in $^{135}$Nd.
- Theoretical models successfully reproduce the observed band properties.

## Abstract

One new pair of positive-parity chiral doublet bands have been identified in the odd-$A$ nucleus $^{135}$Nd which together with the previously reported negative-parity chiral doublet bands constitute a third case of multiple chiral doublet (M$\chi$D) bands in the $A\approx130$ mass region. The properties of the M$\chi$D bands are well reproduced by constrained covariant density functional theory and particle rotor model calculations. The newly observed M$\chi$D bands in $^{135}$Nd represents an important milestone in supporting the existence of M$\chi$D in nuclei.
