摘要
The results of investigation of the fragmentation of relativistic nuclei Be-9 in in emulsion, which is accompanied by the formation of two 1.2-A-GeV He fragments, are presented. The angular measurements of the Be-9 -> 2He events are analyzed. The Be-9 -> Be-8 + n fragmentation channel with the decay of Be-8 from the ground (0(+)) and first excited states into a pair of cv particles appears to be dominant.
