摘　　要：在９２和７１ＭｅＶ１６Ｏ离子与１１５Ｉｎ的相互作用中，用核化学技术测量了２０个反应余核的角分布和微分射程分布．分析了这些余核的生成特征，指出随着碰撞参数的增加，反应机制从全熔合经过质量和动量转移逐渐减小的非完全熔合向直接反应连续演变．与１６Ｏ＋６５Ｃｕ反应相比，１６Ｏ＋１１５Ｉｎ反应中非完全熔合的贡献显著增加．Angular distributions and differential range distributions have been measured with nuclear chemistry techniques for 20 target residues from the reactions of 115In with 92 and 71MeV 16O ions.In terms of the increase of impact parameter,the results indicate continuous evolution of the reaction mechanisms from complete fusion,incomplete fusion to direct reaction involving steadily decreasing transfer of mass and momentum.Contribution of incomplete fusion in 16O+115In reaction is significantly larger than that in 16O+65Cu reaction.
