The intensities of lines belonging to the first negative bands of N^+_2 were measured as a function of the energy of bombarding electrons and the pressure of nitrogen gas. The comparison of the intensities of various lines around 4000 A with and without an interference filter demonstrated that the filter transparent at 3940±100 A is good enough to select the 3914 line from others, provided that the gas pressure is lower than 10^<-3> Torr. As the pressure increases, secondary electrons produced in the gas were found to contribute to the excitation. This can be accounted for in terms of the conventional theory of the secondary electron production and the energy dependence of the excitation cross section of the 3914 line. The latter was found to be approximately reproduced by an empirical formula proposed by Drawin.
