Clustering Features of the 7Be Nucleus in Relativistic Fragmentation

Charge topology of fragmentation of 1.2 A GeV 7Be nuclei in nuclear track emulsion is presented. The dissociation channels 4He + 3He, 23He+ n, 4He + 21H are considered in detail. It is established that the events 6Be + n amount about to 27 % in the channel 4He + 21H.
