PII: S0954-3899(04)79647-4 7 P. J. Phys. G: Nucl. Part. Phys. 30 (2004) 1479–1485 The dissociation of relativistic  nuclei was studied with the photoemulsion
technique. The nuclear photoemulsions have been exposed in the beam of
at themomentum of  GeV/c at the JINR synchrophasotron inDubna. Along
the scanned length  m of tracks,  inelastic interactions have been
found. For the first time the coherent dissociation of the relativistic nuclei
into the  channel in the nuclear photoemulsion has been detected. The
mean free path of this channel in emulsion is equal to  m and corresponds
to the cross section which is equal to  mb. Previously in the dissociation
of the relativistic  nuclei it was found that the main di-cluster configuration
of the ground state of manifests itself as the main channel of coherent
dissociation into  -particle and deuteron. The close values of relative yields
and kinematic features of these two-particle dissociation channels of and
suggest that a similar di-cluster configuration consisting of -particle core
and bound together outer nucleons predominates in the dissociating nuclei at
relativistic energies also. The data presented prove the validity of the relativistic
nuclei dissociation as an effective complementary method for the study of
nuclear structure.
