ABSTRACT: This article provides to descript a consistent of the even-even 182-200Pt isotopes. This has been achieved using the interacting boson model-2 (IBM-2) and including configuration mixing (IBM-2 CM). Our attention is paid to describe the nuclei shape and to their connecting with shaping coexistence phenomenon. Ten isotopes are studied, ranging from the middle of the neutron shell to very near the doubly closed shell at 208Pb. The same Hamiltonian is used for all the nuclei studied, with parameters which are constant or smoothly varying. In this study, we showed the transition between more axially symmetric deformed features of light Pt isotopes to γ-unstable and vibrational isotopes (near spherical shape) for 198-200Pt isotopes.
