[en] Investigation of a new, high efficiency technique for the preparation of laboratory sources of ₆₈Ga by electrocodeposition of ₆₈GeCu³ from dilute alkaline cyanide baths is reported. Procedures are described which have resulted in stable and aherent plates of millicurie intensity. The specific activity of the material is shown to be a critical factor in producing thin (<= 1 mg/cm₂) sources while achieving plating efficiencies in excess of 75%. (orig.)
