The results obtained by estimating the contribution of
and
nuclei to the coherent
dissociation of
,
, and
relativistic nuclei in nuclear track emulsions (“white” stars) are presented.
The selection of white stars accompanied by
leads to a distinct peak appearing in the distribution of the
excitation energy of
ensembles and having a maximum at
MeV.
A
nucleus manifests
itself in the coherent-dissociation reaction
with a probability of
%,
% of
it being due to
decays. The ratio of the branching fractions of the
and
mirror channels
is estimated at
. An analysis of the relativistic dissociation of
nuclei in a nuclear track emulsion
revealed nine
events corresponding to the Hoyle state.
