BEYOND MEAN-FIELD BOSON-FERMION DESCRIPTION OF ODD NUCLEI

We develop a novel theoretical method for calculating spectroscopic properties of those nuclei with odd number of nucleons that is based on the nuclear density functional theory and the particle-boson coupling scheme. A self-consistent mean-field calculation based on the DFT is performed to provide microscopic inputs to build the Hamiltonian of the interacting boson-fermion systems, which gives excitation spectra and transition rates of odd-mass nuclei. The method is successfully applied to identify the quantum shape phase transitions and the role of octupole correlations in odd-mass nuclei, and is further extended to odd-odd nuclear systems.
