摘　　要：在44MeV/A的^(12)C离子和铜的相互作用中,用核化学技术测定了35个靶余核的截面以及前向平均射程.得到了同量异位素分布、质量分布和径向动量转移.质量分布和同量异位素分布与推广的统计模型和蒙特卡罗方法计算结果满意地相符.Cross sections and average forward ranges were determined for 35 target residues from the interaction of copper with 44 MeV/A ^(12)C ions with nuclear chemistry techniques. From these data the isobaric yield distribution, the mass yield distribution and the longitudinal momentum transfer were obtained. The mass yield distribution and the isobaric yield distribution are in good agreement with those calculated from a modified statistical model and corresponding Monte Carlo technique.
