| Popis: | The following article appeared in Applied Physics Letters 101.1 (2020): 014306 and may be found at https://journals.aps.org/prc/pdf/10.1103/PhysRevC.101.014306 The spectroscopic properties of the odd-odd isotopes Cs124-132 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 Xe124-132 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 The work of K.N. is financed within the Tenure Track Pilot Program of the Croatian Science Foundation and the École Polytechnique Fédérale de Lausanne and the Project TTP-2018-07-3554 Exotic Nuclear Structure and Dynamics, with funds of the Croatian-Swiss Research Program, the Croatian Science Foundation, and École Polytechnique Fédérale de Lausanne under the Swiss-Croatian Corporation Program No. TTP-2018-07-3554.
