Аннотация
In dissociation in nuclear track emulsion of 4.5 and 1 A GeV/c12C nuclei, the formation of triplets of α particles in the Hoyle state (the second excited state 0+) is observed. This state is identified by the invariant mass, calculated from pair angles in the α triples in approximation of conservation of momentum per nucleon of the parent nucleus. An estimate of the contribution of the Hoyle state to the dissociation of 12C→ 3α is 10–15%.
