Abstract:Experimental data on fragmentation channels in peripheral interactions of 8B nuclei in nuclear track emulsions are presented. A detailed analysis made it possible to justify selections of events of the electromagnetic-dissociation process 8B → 7Be + p and to estimate its cross section. Events of 10C peripheral dissociation that were observed in the same exposure are described.
