Abstract
Using the suggested model of the electron kinetics of N2 singlet states, the population of the vibrational levels in the molecular nitrogen states (a′)1Σ − u , a 1Π g , and w 1Δ u is calculated for the case when fast auroral electrons penetrate into the Earth’s ionosphere. It is shown for the first time that the population distribution of the vibrational levels v = 0−6 in the state a 1Π g in the auroral ionosphere and also in a laboratory discharge varies with atmospheric pressure insignificantly. Similar calculations for pure nitrogen atmosphere show a considerable increase in the populations of lower vibrational levels (v = 0−2) with rising pressure.
