摘要： 铅和钍在电离阈值附近（16 < E < 45 keV）的绝对L壳层特定电子碰撞电离截面是通过测量LX射线产生截面得到的。 进行了蒙特卡罗模拟以考虑反向散射电子的影响，最终实验结果与使用畸变波玻恩近似和修改的相对论二体碰撞贝斯模型进行的计算进行了比较。 探讨了结果对原子参数的敏感性。 报告了实验结果与理论估计之间的观察到的一致性和差异性及其对特定原子参数的依赖性。 显示英文摘要

摘要： The absolute L subshell specific electron impact ionization cross sections near the ionization threshold (16 < E < 45 keV) of Lead and Thorium are obtained from the measured L X-ray production cross sections. Monte Carlo simulation is done to account for the effect of the backscattered electrons and the final experimental results are compared with calculations performed using distorted wave Born approximation and the modified relativistic binary encounter Bethe model.The sensitivity of the results on the atomic parameters is explored. Observed agreements and discrepancies between the experimental results and theoretical estimates, and their dependence on the specific atomic parameters are reported.
