Abstract

The focusing atomic beam apparatus has been used to measure the spins and hyperfine structure separations of Au198 (2.7 days) and Au199 (3.15 days). The observed spins are 2 for Au198 and 32 for Au199. Observed Δν for Au198 is 21 800±150 Mc/sec, assuming μI to be positive, or 22 500±150 Mc/sec, assuming μI to be negative. Δν for Au199 is 11 110±130 Mc/sec, assuming μI to be positive, or 11 180±130 Mc/sec, assuming μI to be negative. The high Δν for Au198 made it necessary to study that element by observation of multiple-quantum transitions.
