The authors have studied on generation process of N2(A3∑u+) by nitrogen atoms recombination in gas discharge under high E/n condition. In this condition, reduced electric field intensity is very high and varies with position, therefore electron energy distribution is not in equilibrium, especially near the cathode region. So, to make sure the assumption, the authors measured spatial distribution of radiation of N2 1st Positive Band and analyzed electron energy distribution by the MCS (Monte Carlo Simulation) in the case of various E/n.
As a result, the experimental distribution had two peaks, one is a small peak around cathode region, the other is large one at the mid region between electrodes. These results were predicted by the MCS. Consequently, it was confirmed that the generation process of N2 (A3Σu+) varies with position under the high E/n condition.
