Alternative method of the opening of cavities in small icosahedral electrolytic-metal particles

Results of an experiment on the opening of cavities in small icosahedral electrolytic-copper particles by means of an experimental technique alternative to the chemical etching of their surface are presented. This experimental technique is theoretically justified. Original Russian Text ? I.S. Yasnikov, A.A.
