Properties of even 168-178Hf isotopes using IBM-1 and SEF

  • The properties of the ground and excited-state (γ-and β-bands) of 168-178Hf nuclei have been studied. The ratio r(I+2/I) and Eγ (I→ I-2)/I have been calculated as a function of the spin (I) to determine the ground-state evolution. The results indicate that these isotopes have a rotational property SU(3). The energy levels for the ground-state, γ-and β-bands of 168-178Hf have been calculated using the Interacting Boson Model and Semi Empirical Formula (SEF). The parameters of the best fit to the measured data are determined. The behavior of energy and B(E2) ratios in the ground state band are examined.

Abstract: The properties of the ground and excited-state (γ-and β-bands) of 168-178Hf nuclei have been studied. The ratio r(I+2/I) and Eγ (I→ I-2)/I have been calculated as a function of the spin (I) to determine the ground-state evolution. The results indicate that these isotopes have a rotational property SU(3). The energy levels for the ground-state, γ-and β-bands of 168-178Hf have been calculated using the Interacting Boson Model and Semi Empirical Formula (SEF). The parameters of the best fit to the measured data are determined. The behavior of energy and B(E2) ratios in the ground state band are examined.
