Abstract

The lifetimes of members of the ground-state bands in Pt192 and Pt194 have been measured by the Doppler-shift recoil-distance technique. These states were Coulomb excited by 149 MeV Ar40 ions and measurements were carried out in coincidence with backscattered projectiles. The half-lives of the 2+, 4+, and 6+ states in Pt192 and of the 2+ and 4+ states in Pt194 are 48.5±2.5, 4.2±0.2, 1.8±0.7, 45.0±2.4, and 3.7±0.2 ps, respectively. NUCLEAR REACTIONS Pt192,194(Ar′40,γ), E=149 MeV; measured lifetimes of 2+, 4+, and 6+ states in Pt192 and of 2+ and 4+ states in Pt194; deduced B(E2) values, compared with theory.
