    "abstract": "We explore the possibility of shape transitions in proton-neutron systems\ndriven by deformation differences between proton and neutron fluids. Within the\nframework of the proton-neutron interacting boson model, we show that such\ndynamic shape transitions cannot occur in well deformed nuclei but are a\npossibility in transitional nuclei. Likely candidates in the Os-Pt isotopes are\ndiscussed and predictions of the model are compared with the existing data.",
