Production and isolation of 197m,gHg

A new procedure has been developed for isolating no-carrier-added 197m,gHg from 20 to 25 MeV α-particle irradiations of high purity Pt foils. A previously published procedure for isolation of 197m,gHg from 12 to 15 MeV proton irradiations of Au foils has been further characterized. From these procedures two separate methods have been established to isolate, with high separation factors, 197m,gHg from Pt to Au target materials.
