Recent Findings in Relativistic Dissociation of $${}^{}$$B and $${}^{12}$$12C Nuclei

Recent findings related with the unstable nuclei \(^8\)Be and \(^9\)B in the coherent dissociation of relativistic nuclei \(^{10}\)C, \(^{10}\)B and \(^{12}\)C in nuclear track emulsion (“white” stars) are highlighted The \(^8\)Be\(_{g.s.}\) nucleus is manifested in the coherent dissociation \(^{10}\)B \(\rightarrow \) 2He \(+\) H with a probability of 25 ± 5% including 14 ± 3% of \(^9\)B decays. A probability ratio of the mirror channels \(^9\)B \(+\) n and \(^9\)Be \(+\) p is estimated to be 6 ± 1. Reanalysis of relativistic \(^{12}\)C dissociation in lead enriched emulsion revealed nine 3\(\alpha \)-events corresponding to the Hoyle state.
