Nitrogen and nitrogen-helium mixtures were excited by 1.4 MeV protons from a Van de Graaff generator. Intensity versus pressure data from 1 to 600 Torr were recorded and plotted for the first negative band, transitions v 0 to v 0 lambda 3914.4 A, and v 0 to v 1 lambda 4278.1 A and second positive transition v 0 to v 0 lambda 3371.3 A of molecular nitrogen. The theoretical equation from Smelleys work for nitrogen alone was verified and the coefficient BA from Smelleys work was used in this work. A theoretical equation was derived for intensity as a function of partial pressure of nitrogen and helium. As the experimental data shows, a very interesting collisional excitation process was observed, which was not observed for nitrogen-oxygen and nitrogen-carbon dioxide mixtures. Author
