Correspondence between phenomenological and IBM-1 models of even isotopes of Yb

Energy levels and the reduced probability of E2- transitions for ytterbium isotopes with proton number Z = 70 and neutron numbers between 100 and 106 have been calculated through phenomenological （PhM） and interacting boson （IBM-1） models. The predicted low-lying levels （energies, spins and parities） and the reduced probability for E2- transitions results are reasonably consistent with the available experimental data. The predicted low-lying levels （gr-, β1- and γ1- band） produced in the PhM are in good agreement with the experimental data compared with those by IBM-1 for all nuclei of interest. In addition, the phenomenological model was successful in predicting the β2-, β3-, β4-, γ2- and 1＋- band while it was a failure with IBM-1. Also, the 3＋- band is predicted by the IBM-1 model for 172Yb and 174yb nuclei. All calculations are compared with the available experimental data.
