Abstract : Nucleation phenomena in nozzle beams were studied mass spectrometrically. The effect of pressure and orifice size on argon cluster distributions is presented together with a discussion of the factors affecting the interpretation of the cluster ion intensities. An extrapolation to zero orifice size for argon dimer mole fractions yields results in agreement with calculated equilibrium concentrations of Ar2. (Author)
