Sažetak
The spectroscopic properties of the odd-odd isotopes 124–132Cs 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– 132Xe 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 (νh11/2)−1 ⊗πh11/2 configuration. Many of those odd-odd Cs nuclei have been identified as candidates for exhibiting chiral doublet bands.
