摘要
用厚靶-厚收集箔技术测量了45MeV/A^(12)C和^(181)Ta相互作用中余核的生成截面和反冲性质,并将实验得到的质量产额分布与统计碎裂模型进行了比较。根据前向平均反冲射程计算了线性动量转移,在与我们以前工作相比较后指出,在45MeV/A^(12)C离子引起的反应中,中心碰撞的线性动量转移随靶质量而增加,并与引导粒子模型计算结果很好相符。
Cross sections and recoil properties were measured for target residues from the interaction of ^(181)Ta with 45MeV/A ^(12)C ions using thick target-thick catcher foil techniques. The mass yield distribution measured experimentally was compared with a statistical multi-fragmentation model. A comparison of the linear momentum tranfer calculated from the average forward recoil ranges with our previous results indicates that in 45 MeV/A ^(12)C-induced reactions the linear momentum transfer in central collisions increases with target mass, which is in good agreement with calculations on the basis of leading particle models.
