Abstract

The characteristics of low-lying mixed-symmetry states in 158-168Hf isotopes have been investigated in the framework of the interacting boson model. The obtained results  of the low energy spectra,  B(E2) and mixing ratio δ(E2/M1) for all isotopes  are compared with empirical  values .  The effect of the Majrona terms  on the energy levels  have been investigated. The 2ms+  and 1+   states are the lowest mixed-symmetry  for vibrational  158-164Hf nuclei  and  for rotational  166,168Hf  nuclei, respectively
