Abstract : Pure nitrogen and nitrogen-oxygen gas mixtures at pressures from 1 to 800 torr and 300 K were excited by 1.5 MeV protons. Intensity versus pressure data were recorded and plotted for the first negative (B doublet sigma(u)(+) to x doublet Sigma(g)(+)) transition (3914.4A), and second positive (C pi(u) to B triplet pi(g)) transition (3371.3A) in nitrogen. Theoretical equations were derived for the intensity as a function of pressure, which were shown to agree quite well with the experimental data. The following reaction rates, k, and de-excitation cross sections, sigma, were obtained from the derived theoretical equations and the experimental data. (Author)
