The systematic yrast level and electric reduced transition probabilities B(E2)↓ of those nuclei are calculated and compared with the available experimental data. The ratio of the excitation energies of first 4+ and first 2+ excited states, R4/2, is also studied for the O(6) symmetry for these nuclei. Furthermore, as a measure to quantify the evolution, we have studied systematically the yrast level R = EL+1/E2+1 of some of the low-lying quadrupole collective states in comparison to the available experimental data. Moreover, we have studied the systematic B(E2) values, and the moment of inertia as a function of the squared rotational energy for even proton Z = 80 and 110 &lt; N &lt; 118 nuclei indicates the disappearance of back-bending properties. The results of this calculation are in good agreement with the corresponding available experimental data. The analytic IBM-1 calculation of the yrast level and B(E2) values of even-even Hg nuclei is performed in the framework of O(6) symmetry. The contour plot of the potential energy surfaces shows that the nuclei are deformed and have y-unstable-like characters.</p>}, number={8}, journal={Ukrainian Journal of Physics}, author={Hussain, K.
