Abstract. In this study, the ground-state properties of the platinum isotopic chain, 160-238Pt are studied within the covariant density functional theory. The calculations are carried out for a large number of even-even Pt isotopes by using the density-dependent point-coupling and the density dependent meson-exchange effective interactions. Several ground-state properties such as the binding energy, separation energy and quadrupole deformation are discussed and compared with available experimental data, and with the predictions of some nuclear models such as the Relativistic Mean Field (RMF) model with NL3* functional and the Hartree Fock Bogoliubov (HFB) method with UNEDF0 Skyrme force. The shape phase transition for Pt isotopic chain is also studied.
