Abstract

Solidified-gas surfaces are produced In place by a technique similar in principle to that used to form evaporated metallic films. This paper reports a preliminary survey of the adsorptive properties for H2 near 11°K on solidified-gas surfaces of A, N2, O2, H2O, N2O, and CO2. The experimental data are obtained from hydrogen pumping-speed measurements in the 10-9 to 10-7 mm pressure range on solidified-gas substrates of approximately known geometrical surface area.
