International Symposium on Exotic Nuclei, Khanty-Mansiysk, Russia, 17-22 July, 2006

Recent studies of clustering in light nuclei with an initial energy above GeV in nuclear track emulsion are overviewed. The results of investigations of the relativistic nuclei fragmentation in emulsion, which entails the production of fragments, are presented. It is shown that most precise angular measurements provided by this technique play a crucial role in the restoration of the excitation spectrum of the particle system. In peripheral interactions nuclei are dissociated practically totally through the and states of the nucleus.

The results of investigations of the dissociation of a nucleus of momentum GeV/c in emulsion are presented as example of more complicated system. The momentum and correlation characteristics of alpha particles for the channel in the laboratory system and the rest systems of particles were considered in detail.

Topology of charged gragments produced in peripheral relativistic dissociation of radioactive , nuclei in emulsion is studied.
