Abstract: Conversion electron spectra and gentic bonds were studied for neutron- deficient platinum isotopes produced by 660-Mev proton spallation of gold. High specific activity platinum and iridium were separated from irradiated metallic gold. The separation of platinum and iridium was accomplished by the chloride complex anion exchange. The curve of Ir(III) wash-out with 8N HCl is shown. The data on platinum fraction conversion electron spectra are tabulated. The half- life periods of platinum isotopes were found by separating the daughter iridium from the platinum fraction at equal time intervals from 1 to 4 hr. The half life for Pt/sup 186/ and Pt/sup 187/ with activity of Ir/sup 186/ (T=15 hr) and Ir/sup 187/ (T=13 hr) was 2.2 plus or minus 0.5 hr, which is in good agreement with published data. The half life of platinum determined with the activity of daughter iridium (T=3 hr) was 2.6 plus or minus 0.6 hr. According to the previously reported data the new isotope Pt/sup 184/ has a half life of 2.6 plus or minus 0.6 hr. (R.J.V.)
