✦ Synopsis

The production of carbon disulphide micro-clusters (CS ) L , n)11, by adiabatic gas expansion of mixture of CS vapour and Ar is studied by using an electron impact ion source and a double focusing sector field mass spectrometer. The appearance potentials for clusters n)9 decreased as n increased but was not a simple function of 1/n. The appearance pressures of observed clusters showed a slowly increasing dependence on cluster size. Results of measurements of appearance potentials and appearance pressures of selected clusters are described for a range of operating conditions.
