Abstract

Excited states have been observed for the first time in 168Pt and 170Pt using the α-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 168184Pt are presented and discussed within the framework of the interacting boson model.
