New sets of direct electron impact excitation cross sections involving vibrational excited states of H2(including dissociation, ionization andE‐Vprocesses) 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.
