Conversion of a metal microparticle into nanoclusters

The method of generation of metal nanoclusters consists in the injection of a metal microparticle in a vertical flow of a buffer gas where this microparticle stops because of the equality of the gravitation and Stokes forces and rises up along a funnel-shaped tube in the course of evaporation under the action of an external field. The formed metal atoms are transformed into nanoclusters in a cold region of the flow. Parameters of processes involving nanoclusters are analyzed for a silver microparticle in an argon flow.
