In this paper the results of experimental study of hydrogen atoms recombination in positive column and flowing afterglow of direct current discharge in H2+Ar(0-95%) mixture are presented. On the base of ESR measurements the recombination probabilities were obtained on the surfaces of quartz and molybdenum glass at different plasma parameters (100−400 Pa pressure, 5−100 mA discharge cur- rent) and reactor wall temperatures (295−615 K). Apparent activation energies for recombination proc- ess were obtained and recombination mechanism is discussed.
