RT Conference Proceedings T1 Concealed configuration mixing and shape coexistence in the platinum nuclei A1 García Ramos, José Enrique A1 Hellemans, V. A1 Heyde, K. AB The role of configuration mixing in the Pt region is investigated. The nature of the groundstate changes smoothly, being spherical around mass A 174 and A 192 and deformed aroundthe mid-shell N = 104 region. Interacting Boson Model with configuration mixing calculations arepresented for deformations and isotope shifts. The assumption of the existence of two configurationswith very different deformation provides a simple framework to explain the observed isotope shiftssystematics.
