Abstract

Recent findings related with the unstable nuclei ⁸Be and ⁹B in the coherent dissociation of relativistic nuclei ¹⁰C, ¹⁰B and ¹²C in nuclear track emulsion (“white”stars) are highlighted. Selection of the ¹⁰C “white”stars accompanied by ⁸Be (⁹B) leads to appearance of the distinct peak with a maximum at 4.1 ± 0.3 MeV in the excitation energy distribution of 2α2p ensembles. The ⁸Be_g.s. nucleus is manifested in the coherent dissociation ¹⁰B → ²He + H with a probability of 25 ± 5 % including 13 ± 3 % of ⁹B decays. A probability ratio of the mirror channels ⁹B + n and ⁹Be + p is estimated to be 10 ± 1. Reanalysis of relativistic ¹²C dissociation in lead enriched emulsion revealed 9 3α-events corresponding to the Hoyle state.
