“…Excitation energies and transition rates for neutron-rich Yb, Hf, W, Os, and Pt isotopes with atomic masses between 180 and 200 are computed using an interacting boson model Hamiltonian derived from Hartree Fock-Bogoliubov calculations with the microscopic Gogny energy density functional D1M [16]. The IBM-1 model was employed to compute the low-lying positive parity yrast bands and B(E2) values in Hf, W, and Os isotopes with N n = 108 neutrons [17].…”

Interacting Boson Model (IBM-1), Semi Empirical Formula (SEF), and New Empirical Equation (NEE) methods were utilized to determine the energy states of the ground-state (GS), β and γ-bands in the 170-180Os isotopes. The results of the study on the GS, β, and γ bands suggest that IBM-1, SEF, NEE, and existing empirical evidence show some agreement, albeit with some discrepancies. The NEE results for GS, β, and γ bands are more reliable with empirical data than the estimates derived from the IBM-1 and SEF models. The reduced transition probabilities B(E2) of the IBM-1 model correspond well to the experimental data. In the GSB, the energies of the 6+, 8+, and 10+ states are not precisely modeled in the IBM-1 model. The R4/2 values of low-lying energy levels of Os isotopes fluctuate gradually with increasing neutron numbers. The EPS counter indicates that the transition limit of the 170-180Os isotopes has a rotational–vibrational γ-soft transition.

“…The 186 Os nucleus consists of Z = 76 and N = 110. In recent years, even-even isotopes of Tungsten W (Z = 74) and Osmium Os (Z = 76) had been investigated extensively, both theoretically and experimentally [6][7][8]. Al-Jubbori et al [9] studied nuclear structure of rare-earth 172 Er, 174 Yb, 176 Hf, 178 W, 180 Os nuclei.…”

“…Yrast states of up to I π = 12 + in 186 W (Z = 74, N = 112) and 186 Os (Z = 76, N = 110) isobars have been found by π h -8 11/2 i -14 13/2 configurations for double magic Z = 82, N = 126 in 208 Pb nucleus. The quadrupole E2 transitions incur collective properties in 184 W and 184 Os isobars, which had been studied both theoretically and experimentally [6][7][8]. It is interesting to observe the collective properties of nuclei far away from the closed shell of the 208 Pb nucleus, where the double magic numbers Z = 82 and N = 126 found a closed shell in 208 Pb nucleus.…”

In this study, we applied the Interacting Boson Model (IBM-I) to compute the electric reduced transition probabilities B(E2)\(\downarrow\) of even-even neutron rich \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars. The ratio \(R_{4/2} = E(4_{1}^{+}) / E(2_{1}^{+})\) has also been calculated for those isobars and the SU(3) symmetry for those isobars has been reported. \(E(4_{1}^{+})\) and \(E(2_{1}^{+})\) indicate the energy level of \(4_{1}^{+}\) and \(2_{1}^{+}\), respectively. We have described the strength of B(E2) in W.u. for \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars of some of the low-lying quadrupole collective states in contrast to obtainable measured data. The electric reduced transition probabilities B(E2)\(\downarrow\) from yrast state gamma transition from \(12_1^{+} \rightarrow 10_1^{+}\), \(10_1^{+} \rightarrow 8_1^{+}\), \(8_1^{+} \rightarrow 6_1^{+}\), \(6_1^{+} \rightarrow 4_1^{+}\), \(4_1^{+} \rightarrow 2_1^{+}\) and \(2_1^{+} \rightarrow 0_1^{+}\) and other bands states and B(E2) ratio of \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars have been compared with obtainable measured data and other previous studies. Also calculated were the systematic strength of B(E2), intrinsic quadrupole moments, and deformation parameters of even-even \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars. The data from these calculations are in good matching with the obtainable measured data. The IBM-I model for the strength of B(E2) has been systematically deduced in SU(3) limit for a few yrasts states transitions in \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars.
