Detailed study of relativistic 9Be → 2α fragmentation in peripheral collisions in a nuclear track emulsion
Recent studies of clustering in light nuclei with an initial energy above 1 A GeV in a nuclear track emulsion are overviewed. The results of investigations of the relativistic 9Be nuclei fragmentation in emulsion, which entails the production of α particles, 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 α particle system. In peripheral interactions 9Be → 2α nuclei are dissociated practically totally through the 0+ and 2+ states of the 8Be nucleus.
