Abstract

The Pt194,196,198(t,p) reactions have been measured with 17 MeV tritons on enriched and natural Pt targets. The level structure of Pt200 is probed for the first time, and several new excited O+ states have been identified in Pt196,198,200. Systematics in level structure of Pt192-200 are fairly constant, although there is evidence that Pt198,200 are becoming more vibrational in structure, with the -unstable shape of the lighter Pt nuclides becoming more oblate-like. Systematics of L=4 strengths are considered and can be qualitatively understood. The (t,p) strengths measured in the present study are combined with earlier Pt(p,t) and Os(t,p) measurements and compared with the systematics of two-neutron transfer strengths predicted by the interacting boson approximation, schematic, boson expansion, and pairing vibration models.
