N2 - The results of the study of processes occurring in supersonic flows of gas mixtures under the influence of high voltage electron beam are presented. The research was performed on the gas-dynamic complex of experimental installations located in the Department of Applied Physics of Novosibirsk State University. Spectral methods and molecular beam mass spectrometry were used to diagnose the processes. A significant difference in the clustered argon mass spectra was found in comparison of spectrum recorded during ionization by a quadrupole mass spectrometer own ionizer and spectrum obtained with the transport of ions formed by an electron beam in the jet through a skimmer to the mass spectrometer detector (without using an ionizer of spectrometer). The second variant of gas flow ionization presents the possibility of registering the mass spectrum of a hydrocarbon series with features indicating the occurrence of heavier hydrocarbons in the jet. The mechanism of intracluster energy exchange with the transfer of excitation initiated by electrons with subsequent intense radiation at certain wavelengths of a neutral argon atom was detected and identified.
