Abstract : The results of an detailed analysis of experimental size distributions of particle samples prepared by the gas evaporation technique GET are reported. By considering both growth processes involved in the particle preparation by GET i.e. growth by absorption of metal atoms and growth by coalescence, the shapes of the observed size distributions from normal-like to log-normal are interpreted as the result of the superposition of two oppositely skew bell shaped size distributions. The one - due to coalescence - is according to reference 1 of log-normal type. The other - due to absorption growth - is assumed to be qualitatively similar to the size distribution predicted for particle growth on a substrate by interface reaction controlled atom transport.
