N2 - Recently, great interest in the analysis of the ArH+ ion electronic states in a number of scientific studies,in which there are significant discrepancies between the available experimental measurements and theoretical results has been shown. The most efficient production of protonated argon was achieved by electron ionization of the supersonic flows of argon and hydrogen mixtures. In this article, the clustering influence onthe formation of protonated monomers and small argon clusters is considered. Two variants of ionization of supersonic fluxeswere used: by a high-voltage electron beam immediately in thejet with ion registration by transport to the mass spectrometer of a molecular beam system (HVEB method) or by a low-energyelectron beam directly in the mass spectrometer detector (EBMSmethod) of molecular beam skimmed from a supersonic jet. The effect of stagnation pressure and the average cluster size in a gasstream on the argon-hydrogen compound ions formation have been studied. The parameters of the most effective ion formation of such compounds in the considered range of gas-dynamic parameters are determined. Suggestions about the type (ArnHm)(+)ions formation mechanism in a clustered stream are considered
