Contribution of the unstable nuclei , and into coherent dissociation events (“white” stars) of relativistic nuclei , and is under study on the basis of a nuclear track emulsion exposed to beams of the JINR Nuclotron. Distributions over the opening angle of -pairs indicate to a simultaneous presence of virtual and states in the ground states of the and nuclei. The core is manifested in the nucleus with a probability of %, Selection of the “white” stars accompanied by () leads to the appearance in the excitation energy distribution of “quartets” of the distinct peak with a maximum at MeV. decays are presented in % and % in the of the all “white” stars. decays are identified in “white” stars constituting % of the “white” stars. The nucleus is manifested in the “white” stars with a probability of %. For the case yield of nuclei with the respect to is about a factor of higher than .
