Abstract

The experimental diffraction patterns from the Kr cluster beams are compared with the diffraction functions calculated for the rare-gas clusters consisting of 3×103 and 1×104 atoms/cluster. The experimental data are in good agreement with the calculated which assume a fcc structure with a constant number of intercrossing defect planes. This provides supplementary support for the determining role of the kinetic factor in the formation of the crystalline phase of the clusters. Possible causes of the absence of considerable changes in the densitogramms with increasing the cluster size by more than one order of magnitude (see M.-F. de Feraudy, G. Torchet, B. W. van de Waal [ISSPIC (1998)]) are proposed.
