Abstract：
A nuclear emulsion stack bombarded by 200GeV/nucleon oxygen nuclei has been analyzed.The measurement of a ternary fragmentation event of a relativistic oxygen nucleus into three helium nuclei and 22 minimum ionizing particles has been performed.The mechanism of the fragmentation processes has been discussed.The fragmentation phenomena of the relativistic oxygen nuclei provied a direct experimental evidence for the cluster model of the oxygen nuclei.
