• Shape-phase transition
• interacting boson model
• energy spectra
• B(E2) transition rates
• critical point

In this paper, by using the SO(6) representation of eigenstates and transitional Interacting Boson Model (IBM) Hamiltonian, the evolution from prolate to oblate shapes along the chain of Hg isotopes is studied. Parameter-free (up to overall scale factors) predictions for spectra and B(E2) transition rates are found to be in good agreement with experimental data for 200-204Hg isotopes which are supported to be located in this transitional region.
