Abstract
The properties of the ground and excited-state bands of 178−188Os nuclei have been studied. The ratio E γ /I has been calculated as a function of the spin (I) to determine the ground-state evolution. The ratio between the energies of the (I + 2) and (I) states as a function of the spin (I) has been drawn to determine the property of the ground-state band. The energy levels for the ground-state band of 178−188Os have been calculated using Bohr–Mottelson model, Interacting Boson Model, interacting vector boson model and Doma–El-Gendy relation. The negative parity band of 178−188Os has been also calculated using above models. The γ-band of 178−188Os isotopes and β-band states of 178,182,184Os isotopes have been calculated using Interacting Boson Model. The parameters of the best fit to the measured data are determined.
