Abstract
The spherical to -unstable nuclei shape-phase transition in odd- nuclei is investigated by using the dual algebraic structures and the affine Lie algebra within the framework of the interacting boson-fermion model. The new algebraic solution for odd- nuclei is introduced. In this model, single and 3/2 fermions are coupled with an even-even boson core. Energy spectra, quadrupole electromagnetic transitions, and an expectation value of the -boson number operator are presented. Experimental evidence for the transition in odd- Ba and Rh isotopes is presented. The low-states energy spectra and values for these nuclei are also calculated and compared with the experimental data.
