Studies of light nicleus clustering in relativistic multifragmentation processes

Abstract

We give an overview of results and prospects of nuclear clustering studies on the grounds of the observations of interactions of light stable and radioactive nuclei with an initial energy above 1 A GeV in nuclear emulsions. Thank to the best spatial resolution and the full solid angle acceptance provided by nuclear emulsions, such an approach allows one to obtain unique and evident observations reecting cluster-like features in light nuclear structures. New results on dissociation of $^7$Be in very peripheral interactions with emulsion nuclei are presented. The importance of this research for the physics of few body nuclear systems and the related problems of nucleosynthesis is noted. The paper is illustrated with characteristic images obtained by means of a microscope equipped with a CCD camera. The discussed explorations are provided with the beams of the Synchrophasotron and Nuclotron of JINR, Dubna. Future investigations are suggested to be carried out in relativistic beams of He, Be, B, C, and N isotopes.
