摘要：

Study of production of ensembles of alpha-particle triples associated with the Hoyle state (the second excited state 0(2)(+)of the C-12 nucleus) in peripheral dissociation of relativistic C-12 nuclei is started. Stacks of pellicles of nuclear track emulsion exposed to C-12 of energy from hundreds MeV to few GeV per nucleon serve as the material of the study. The Hoyle state decays are reconstructed via measurements of emission angles of alpha-particles with accuracy that allows one to identify the unstable Be-8 nucleus. A role in the Hoyle state of alpha-particle bonds corresponding to Be-8 is determined.
