The Interacting Boson Models, IBM1 and IBM2, analyzed in their O(6) limit are used to describe the properties of the 190Hg isotope. A fitting procedure is used to determine the most accurate parameters to the calculated energy levels of this nucleus. The calculated ground, gamma, and beta bands energy of each model are compared to the previously measured data. Quadrupole electromagnetic transition strengths for 190Hg, obtained from both IBM1 and IBM2, are presented and associated with previously experimental results. Finally, potential energy surfaces (PES) of 190Hg in the dynamical symmetry O(6) of the IBM1 as an occupation of the restriction of the deformation are determined and discussed. All calculations are satisfied with experimental data.
