Recent studies of clustering in light nuclei with an initial energy above 1 A GeV in nuclear track emulsion are overviewed. The results of investigations of the relativistic 9Be nuclei fragmentation in emulsion, which entails the production of He 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 {alpha} particle system. In peripheral interactions 9Be nuclei are dissociated practically totally through the 0+ and 2+ states of the 8Be nucleus.The results of investigations of the dissociation of a 14N nucleus of momentum 2.86 A GeV/c in emulsion are presented as example of more complicated system. The momentum and correlation characteristics of {alpha} particles for the 14N{yields}3{alpha} + X channel in the laboratory system and the rest systems of 3{alpha} particles were considered in detail. Topology of charged fragments produced in peripheral relativistic dissociation of radioactive 8B, 7Be nuclei in emulsion is studied.
