New sets of direct electron impact excitation cross sections involving vibrational excited states of H2 (including dissociation, ionization and E‐V processes) have been calculated by Gryzinski fomulation. These rates are then inserted in a numerical code based on the simultaneous solution of Boltzmann equation, of vibrational kinetics and H, H− production rates. Comparison of theoretical and experimental results shows satisfactory agreement for the electron temperature and electron density, while some discrepancy does exist on the negative ion concentration.
