DIFFUSION COEFFICIENT MEASUREMENTS FOR GAS MIXTURE OF ATOMIC AND MOLECULAR HYDROGEN

Abstract

The multicomponent diffusion coefficient D(H,H2) was evaluated from measurements of the relative atom density in a semi-infinite catalytic cylinder as a function of (a) distance from the atom source under steady-state conditions, and (b) time during the transient condition associated with removal of the atom source after attainment of steady state. An electron spin resonance spectrometer was employed for atom-density measurements and a radio-frequency discharge for atom production in the total gas-pressure range from 0.85 to 2.6 torr.
