Evaporation of clusters during free flight after homogeneous nucleation in nozzle expansion

This work deals with the evaporation of clusters in their flight from the condensation zone in the nozzle until their detection. This time is of order ${10}^{\ensuremath{-}5}$ - ${10}^{\ensuremath{-}3}$ sec, depending on the experimental setup. It is shown that the cluster concentrations converge to a characteristic distribution in a short time (\ensuremath{\sim} ${10}^{\ensuremath{-}8}$ sec) independently of the initial conditions. It is also concluded that both Ar and Xe small clusters arrive solid at the detection zone.
