Excited states have been observed for the first time in 168Pt and 170Pt using the a-decay recoil-tagging technique. The trend of decreasing deformation moving away from the N = 104 mid-shell continues for 170Pt but the structure of 168Pt is significantly different. The low spin level energy systematics in 168-184Pt are presented and discussed within the framework of the interacting boson model.
