Electron-impact excitation cross sections from ground level of the atomic state (Ref. 27), (Ref. 33), and (Ref. 30) molecular electronic states, and from excited state (Ref. 34).
Experimentally obtained electron energy probability functions for (a) -mode and (b) -mode operation regimes.
(a) Experimentally obtained band sequence of the first positive system; (b) synthetically generated sequence for the best fit vibrational temperature.
Relative vibrational distributions of (a) electronic state obtained from integrated band intensities of sequences; (b) electronic state calculated based on relative vibrational distribution of electronic state and Franck-Condon factors.
