Abstract: The progress of the study of unstable states in relativistic dissociation events of light nuclei in nuclear emulsion is presented. Identification of these states is possible by means of the invariant mass determined from the most accurate and complete measurements of relativistic fragment emission angles in the approximation of conservation of momentum per nucleon of the parent nucleus. It is established that excitations 1 2 C (0 2 +) and 1 2 C (3 −) lead in the dissociation 1 2 C → 3 α and 1 6 O → 4 α. The contribution of 9 B and 1 2 C (0 2 +) decays to the leading channel of 3 HeH dissociation of the 1 4 N nucleus is estimated. The motivation and the beginning of the analysis of the relativistic dissociation 1 6 O → 1 2 C α are presented. The presented relativistic dissociation events at the 7 Be → 6 Li p and 1 1 C → 7 Be α coupling threshold point to the prospect of moving beyond α -particle clustering. [ABSTRACT FROM AUTHOR]
