We will explain the aspects of 180Hg nucleus through the interacting boson model (IBM-1) and IBM-2. This nucleus is expected to be typical in the limit of the U(5) symmetry which is deliberate to elucidate the properties of 180Hg nucleus. A suitable method for fitting is expected to improve the best parameters for a convinced calculated energy level of this nucleus. The intended three energy bands such as ground, gamma, and beta bands in both models are studied and compared with the data obtained earlier by M.A. Al-Jubbori, I. Hossain, F.I. Sharrad, and N. Aldahan. The strengths of quadrupole electromagnetic transitions B(E2) of this nucleus in IBM-1 and IBM-2 models are calculated and matched with reasonable earlier measured data. The potential energy surfaces (PES) of this nucleus for the distortion parameter in the U(5) symmetry in IBM-1 is analyzed. All data on 180Hg nucleus are well consistent with available measured data.
