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

Abstract

Measurements of the adsorption of nitrogen on a polycrystalline tungsten wire and of carbon monoxide on molybdenum were continued (see AD-434 094). The saturation coverage of nitrogen on tungsten at room tempera ture was shown to be a function of the steady-state pressure and varies from 1 x 10 to the 14th power to 2.5 x 10 to the 14th power molecules/sq. cm. over the pressure range 10 to the -9th power to 10 to the -6th power torr. The adsorption of carbon monoxide on molybdenum at room temperature increases the work function of molybdenum over its initial value by 0.1 to 0.2 electron volts at saturation. (Author)
