STUDY OF ADSORPTION OF GASES ON SOLIDS IN THE HIGH VACUUM RANGE

Abstract

An investigation of the interaction of nitrogen with a hot tungsten filament showed that a chemical pumping effect occurs. The magnitude of this effect and its variation with temperature is discussed. Preliminary results on the study of the effect of adsorbed oxygen on the work function of molybdenum at room temperature indicated that there are three stages in the adsorption process: during the first two stages, there is a rapid increase in the work function, whereas in the last stage there is a small increase and very slow rate of rise in work function.
