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.
