Experimental data are available which suggest that the fast production of electronic excited states in electron-irradiated helium- (or neon-) nitrogen mixtures is due to the interactions of subexcitation electrons. These systems - helium or neon with trace only amounts of N/sub 2/ - lend themselves to theoretical analysis by various methods. Using only well-established cross-section data for inelastic processes in these systems allows the time dependence of the evolution of emission from the C/sup 3/II/sub u/ state of N/sub 2/ to be calculated. The results of these calculations show (i) support for the subexcitation electron mechanism; (ii) that the continuous slowing down approximation is inappropriate in these systems; (iii) that a Monte-Carlo technique gives satisfactory agreement between theory and experiment; and (iv) that more reliable data and a closer analysis of it will assist further development of these ideas.
