Recent results of surface produced negative ions are presented. Two low work function metal surfaces have been studied, barium and magnesium, in combination with several plasma generators; RF- and DC-filament discharges. The negative ion yield for barium is about 5 to 6 times larger than magnesium. This ratio is confirmed by model calculations on resonant charge exchange.
