Deactivation of N2 A/super 3/Sigma/sub u/+ molecules in the aurora.

Recent rocket observations of the molecular nitrogen Vegard-Kaplan system in the aurora have been reinterpreted using an atmospheric model based on mass spectrometer measurements in an aurora of similar intensity at the same time of year. It is found that the population rates of the considered levels in the aurora are accurately determined by radiative cascade from two other states excited by direct electron impact. In some bright auroras the role of NO in quenching the lower vibrational levels of the A state is significant. The conclusions are based on a number of relevant auroral observations in combination with calculations using electron cross section and transition probability measurements by Shemansky and Broadfoot (1971).
