Kinetics of Cluster Formation During Rapid Quenching
A numerical scheme has been developed to evaluate quantitatively the non-steady state kinetics of cluster generation during the rapid quench of a vapor system. Our method is particularly suitable to deal with the supersonic jet expansion of vapors. Based on this calculation scheme, we have carried out a systematic study on metal cluster formation in nozzle jet beams. We have also introduced the icosahedral structure into our calculation for the cluster size distribution of noble gas elements. Most of the “magic numbers” found experimentally appeared in our calculated spectrum.
