The formation of Be-8 nuclei and their role in the fragmentation of light nuclei

摘要

In the processes related to nuclear clustering in light nuclei, a special role belongs to the Be-8 nucleus. This nucleus is the transition state through which a considerable fraction of alpha particles, the fragments of all relativistic nuclei, is formed. The emphasis of this review is on the experimental features involved in identifying Be-8 nuclei in the fragmentation of relativistic B-10 nuclei, chosen due to the fact that they are the lightest nuclei in which this cluster can be formed. The formation probabilities of Be-8 nuclei are calculated for the fragmentation of relativistic B-10, C-12, and O-16 nuclei and compared with the experimental data. It is shown that the suggested formation mechanism of this clustering during the fragmentation of relativistic nuclei is correct, as the calculations performed on its basis are experimentally corroborated.
