The electron-diffraction study of the clusters generated in supersonic jets of carbon dioxide has been carried out. The average size of the clusters varied from 4×102 to 2×104 mol/cluster. The analysis of the diffractogramms obtained demonstrates that the aggregations of the above sizes have a structure of a bulk crystal. The clusters with an average size less than 1.7×103 mol/cluster display for the first time the stacking faults the density of which increases with decrease in aggregation size. It is found that the stacking fault density in the (CO2)N clusters is appreciably less than that in the case of rare gases.
