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