Abstract :
The nuclides 168–170Pt were produced by bombarding isotopically enriched 92,94Mo targets with 336, 348 MeV 78Kr ions. Prompt γ rays were detected at the target position and provided a selection criterion for the 168–170Pt nuclei. This technique enables the problem of the background from higher-energy α decays in the spectrum to be circumvented. The Pt nuclei were separated in flight using the gas-filled separator RITU and implanted into the GREAT spectrometer, which was used to study subsequent α decays. The α -decay branching ratios of 164–166Os were deduced from the fraction of selected 168–170Pt nuclei correlated with α decays of 164–166Os. The resulting branching ratios agree with the literature values but can have improved precision.
