摘要
使用离线γ能谱法测定了46MeV/A^(12)C离子和^(93)Nb相互作用中厚靶反冲射程,得到了最大线性动量转移和平均线性动量转移,和已有工作比较后指出,相应于中心碰撞的最大线性动量转移在轻靶和中重靶范围内与靶质量无关,但明显低于与^(238)U碰撞的线性动量转移.平均线性动量转移显示了与弹核和靶核不对称性的强烈依赖关系.
Thick-target recoil ranges of the residues from the interaction of ^(93)Nb with 46 MeV/4 ^(12)C tons have been measured by off-line γ-ray spectroscopy. From these data the maximum linear momentum transfer and the mean linear momentum transfer were obtained. A comparison with other results indicates that the maximum linear momentum transfer, corresponding to central collisions is independent of the target mass numbers for light and intermediatmass targets. However the mean linear momentum transfer shows a strong dependence of the projectile-target asymmetry.
