In dissociation in nuclear track emulsion of
and
GeV/c
nuclei, the formation of triplets
of
particles in the Hoyle state (the second excited state
)
is observed. This state is identified by the invariant
mass, calculated from pair angles in the
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
is
