摘要：

The results obtained by estimating the contribution of 8Be and 9B nuclei to the coherent dissociation of C-10, B-10, and C-12 relativistic nuclei in nuclear track emulsions ("white" stars) are presented. The selection of white stars accompanied by 9B leads to a distinct peak appearing in the distribution of the excitation energy of 2 alpha 2p ensembles and having a maximum at 4.1 +/- 0.3 MeV. A 8Be nucleus manifests itself in the coherent-dissociation reaction B-10 -> He-2 + H with a probability of (25 +/- 5)%, (14 +/- 3)% of it being due to 9B decays. The ratio of the branching fractions of the B-9 + n and Be-9 + p mirror channels is estimated at 6 +/- 1. An analysis of the relativistic dissociation of C-12 nuclei in a nuclear track emulsion revealed nine 3 alpha events corresponding to the Hoyle state.
