[Study on concentration modulation spectra of the molecular ion beam by AC glow discharge].
An experimental apparatus using an AC discharge was developed for producing molecular ion beam. The emission spectral intensity of N2+ is stronger than that of N2, and a very high ratio of N2+ (B)/N2 (C) up to 6:1, was achieved in N2 discharge. The effects and processes of N2 discharge, and the concentration modulation spectra were studied. The vibrational temperature and rotational temperature of N2+ molecular ions beam were calculated to be 3 310 and 282 K respectively from the emission spectra.
