摘　　要：在96 MeV^(16)O离子轰击下,测量了^(16)O+^(64)Ni反应出射碎片(α直至O元素)的Wilczynski图和角分布,并提取出DIC截面和反应时间等物理量;讨论了反应的DIC特征;看到了出射碎片α和Li主要来源于复合核蒸发的迹象。The angular distributions and Wilczynski plots of emitted fragments from He to O in reaction of ^(16)O+^(64)Ni at 96 MeV have been measured. The DIC cross section and intereaction time were obtained. DIC character of the reaction was discussed. The trace which shows that the emitted fragments of He and Li mainly come from the evaporation process of compound nuclei emerged.
