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.
