Abstract

We present some new data concerning the specific excitation of the 2+ and 1- nitrogen band systems in a hollow cathode plasma in N2 + He gas mixtures. The relative intensities of the band heads of these both systems and of He spectral lines distributions versus the partial N2 pressure in the N2 + He gas mixtures, and the upper vibrational excited level population against the same parameters give us a good representation about the stimulation or inhibition of the nitrogen 2+ and 1- bands excitation..
