Abstract:
The low-lying collective energy spectra of cadmium even isotopes are calculated exactly by means of microscopic IBM-2 approach which is based on the Dyson boson expansion and the modified Jancovici-Schiff substitution. The exciting properties of valence proton hole are-analyzed.The results show that the mixed-symmetry states and full-symmetry states of cadmium even isotopes are well described by IBM-2.
