The aim of this work is to describe the results of calculation of multipole mixtures in some even-even Hf isotopes. Deformed nuclei have been studied for many years and an enormous quantity of detailed spectroscopy now exsts. But et, our understanding of these nuclei remains suprisingly limited. The medium-to heavy-mass hafnium (Hf) isotopes are located in the rare-earth mass region where well-deformed nuclei can be populated to very high spin. The IBA model [1] has been applied to deformed nuclei [2], usually with considerable success [3, 4]. As a result of the phenomenological description of deformed nuclei in IBM, Hf isotopes has been occupied along the SU(3)-O(6) leg of the IBM triangle. In this work, we have carried out calculations for such isotopes and obtained reasonably good agreement with emprical systematics in the region. The aim of this work is to describe the results of calculation of multipole mixtures in Hf-174,Hf-176,Hf-178,Hf-180.
