IBM-1 Calculations of Low-Lying Excited Levels and Electric Transition Probabilities B(E2) on the Even-Even 174-180Hf Isotopes

In this paper, the interacting boson model (ibm-1) is discussed and employed for calculating the energy levels and the electromagnetic transition probabilities b(e2) of the even – even 174-180hf isotopes. these isotopes have been investigated based on two different arrangements; i.e., the dynamical symmetry of 176-180hf isotopes, su(3) (deformed nuclei) and the dynamical symmetry of 174hf isotope in transition region su(3)-o(6). the determined values using the ibm-1 hamiltonian showed significant agreement with the experimentally reported energy levels and b(e2) values. the model provides a fast and accurate prediction method of energy levels and b(e2) values.
