%X Using N~+_2 as the molecular probe, we investigate the ionization behavior of the nitrogen molecule buffered in different rare gases (helium and neon) by optical heterodyne velocity modulation spectroscopy . The spectral intensity of an individual rovibronic line of N~+_2 is propor tional to the product of the velocity modulation index and the concentration of N~+_2. Therefore, the relative ionization depth can be deduced viameasuring the spectral intensity in different buffer gases.
