The isotope Ir/sup 196/ has been reported to have a half life of ~ 9 days and to emit BETA /sup -/ particles with a maximum energy of about 0.08 Mev. Using deuteron-bombarded enriched isotopes of platinum, it is shown that the previous mass assignment was incorrect. It is suggested that the ~ 9-day activity found in deuteron bombardments of natural platinum is due to Ir/sup 189/ and I/sup 190/ roduced by the (d,n) reaction on osmium impurities. An experimental upper limit of 5 hours for the Ir/sup 196/ halflife can be set by these experiments. Rough cross sections for the (d, alpha ) reaction on Pt/sup 194/ and Pt/sup 196/ are given for several deuteron energies from 9.6 to 20.4 Mev. (auth)
