Ionization mechanism in Comet was simulated in laboratory using gun-produced plasma stream and gas cloud from F. A. V. Diagnostic tools were an optical spectrometer, a Kerr cell camera and an image converter camera. Helium gas cloud is ionized by hydrogen or helium plasma stream, but not ionized by argon or nitrogen plasma stream. It is revealed that a neutral gas cloud is ionized by electrons heated in a shock wave created in the mutual gas cloud-plasma stream interaction. Observing H_β in the interaction of hydrogen plasma stream with various gas clouds, the intensity of H_β is the strongest when hydrogen plasma stream interacts with helium gas cloud. This is explained by the excitation transfer
