N2 - The influence of a monatomic carrier gas on cluster formation in supersonic methane jets is studied. The formation of methane clusters in a mixture with condensed argon and non-condensable helium with the same gas-dynamic parameters is then compared. It is shown that the methane clusters' formation intensity is extremely low both within a jet of pure methane, and in a mixture with carrier argon. The methane condensation process dependence on the properties of a carrier gas and the methane volume fraction in the mixture at the selected gas dynamic parameters of the flow is demonstrated. The effect of dissociative methane ionization and the fragmentation of methane clusters in the mass spectrometer detector on the recorded mass spectrum is established. The cluster methane ions protonation and the increase in their fraction with increasing clusters are recorded. Finally, magic numbers for methane clusters are found.
