Abstract

Properties of the odd-mass Eu isotopes are investigated in the framework of the interacting boson-fermion approximation (IBFA) model. It is shown that in the IBFA model a rather detailed and yet simple description can be given of odd-mass nuclei ranging from spherical 147Eu to deformed 155Eu. Calculated excitation energies, proton separation energies, E2 and M1 transition probabilities, quadrupole and magnetic moments and spectroscopic factors for single-proton transfer are compared with experiment. The model parameters determined are compared with the predictions of a simple microscopic theory.

      The problem is also of interest to the condensed matter physics community where one is interested in the motion of fermionic impurities in a bath of bosons [28].) Studies of QPTs in odd–even nuclei were implicitly initiated years ago by Scholten and Blasi [29]. Several explicit studies have recently been made by Alonso et al. [30–32] and by Böyükata et al. [33], who also have suggested a simple form of the IBFM Hamiltonian particularly well suited to study QPTs in odd–even nuclei because of its supersymmetric properties.
