The structural features of {sup 10}B are studied by analyzing the dissociation of nuclei of this isotope at an energy of 1 A GeV in nuclear track emulsion. The fraction of the {sup 10}B → 2He + H channel in the charge state distribution of fragments is 78%. It was determined based on the measurements of fragment emission angles that unstable {sup 8}Be{sub g.s.} nuclei appear with a probability of (26 ± 4)%, and (14 ± 3)% of them are produced in decays of an unstable {sup 9}B{sub g.s.} nucleus. The Be + H channel was suppressed to approximately 1%.
