Abstract
In the form of two quasi-particles coupled to a core described by the IBM-1 and Triaxil Rotor models, the high-spin states of the Ba and Ce isotopes are studied. Bands based on both (vh11/2)-2 and (configurations are considered, which is found to be appropriate for this region to better explain band-crossing systems. Between the recent experimental data and the calculated energy spectra and electric transition probability, fair agreement is achieved.
