DC GLOW-DISCHARGE IN NEON MIXTURES WITH HYDROGEN AND METHANE

The concentrations of neon and hydrogen atoms in metastable and resona nce states, as well as the concentration of atomic hydrogen, were dete rmined in a de glow discharge in mixtures of neon with H-2 (1 vol %) a nd CH4 (1 vol %) at pressure 13-520 Pa and a discharge current ranging from 5 to 100 mA. The mechanisms of excitation, ionization, and disso ciation processes observed experimentally were studied. it was demonst rated that the emitting states of neon and hydrogen were excited in a stepwise mode from the metastable and resonance states, and the main i onization channel was Penning ionization.
