The nuclides 168-170 Pt were produced by bombarding isotopically enriched 92,94 Mo targets with 336, 348 MeV 78 Kr ions. Prompt g rays were detected at the target position and provided a selection criterion for the 168-170 Pt nuclei. This technique enables the problem of the background from higher-energy a 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 a decays. The a-decay branching ratios of 164-166 Os were deduced from the fraction of selected 168-170 Pt nuclei correlated with a decays of 164-166 Os. The resulting branching ratios agree with the literature values but can have improved precision.
