“…The alignment plots of band 1, band 2 and the known πh 11/2 ⊗ νg 7/2 band, reported in Ref. [14], of 126 Cs are shown in Fig.3 where the πh 11/2 ⊗νg 7/2 band exhibits a sharp backbend at ω =0.41MeV caused by the rotational alignment of the first pair of h 11/2 neutrons. The absence of a band crossing at this frequency for bands 1 and 2 in Fig.…”

The candidate chiral doublet bands recently observed in 126 Cs have been extended to higher spins, several new linking transitions between the two partner members of the chiral doublet bands are observed, and γ−intensities related to the chiral doublet bands are presented by analyzing the γ−γ coincidence data collected earlier at the NORDBALL through the 116 Cd( 14 N, 4n) 126 Cs reaction at a beam energy of 65 MeV. The intraband B(M 1)/B(E2) and interband B(M 1) in /B(M 1) out ratios and the energy staggering parameter, S(I), have been deduced for these doublet bands. The results are found to be consistent with the chiral interpretation for the two structures. Furthermore, the observation of chiral doublet bands in 126 Cs together with those in 124 Cs, 128 Cs, 130 Cs and 132 Cs also indicates that the chiral conditions do not change rapidly with decreasing neutron number in these odd-odd Cesium isotopes.

The spectroscopic properties of the odd-odd isotopes 124−132 Cs have been studied within the interacting boson-fermion-fermion model based on the Gogny-D1M energy density functional framework. Major ingredients to build the interacting boson-fermion-fermion Hamiltonian, such as the (β, γ)-deformation energy surfaces for the even-even core nuclei 124−132 Xe as well as single-particle energies and occupation probabilities of the odd nucleons, have been computed microscopically with the constrained Hartree-Fock-Bogoliubov method. A few coupling constants of the boson-fermion and residual neutron-proton interactions are fitted to reproduce with a reasonable accuracy the experimental excitation energy of the low-lying levels of the odd-mass and odd-odd nuclei. The method is applied to describe the low-energy low-spin spectra of the odd-odd Cs nuclei and the band structures of higher-spin higher-energy states, mainly based on the νh 11/2 ⊗ (πh 11/2 ) −1 configuration. The nucleus 128 Cs, has been identified as the best candidate for exhibiting chiral doublet bands.
