ABSTRAKT

We present a new method for the calculation of electron-impact electronic and vibronic rate coefficients in nitrogen plasmas in which rotational levels are taken into account, and we analyze differences with existing methods. High-lying rotational levels, neglected in previous methods, are shown to have a major influence on dissociation rates. Calculated vibronic depletion rates of the B state of N2 under the experimental conditions of Ref. [1] are significantly smaller than predissociation rates.
