摘要: 基于平均散射截面概念,结合Mott截面,计算E≤10 keV范围低能电子在水中弹性散射的微分散射截面、总散射截面及弹性散射角概率分布,与应用Rutherford模型的计算结果及实验结果符合较好.在此基础上,给出一个低能电子在水中弹性散射的模拟方法,既严格可靠,又能够方便地应用于低能电子在水中径迹结构的模拟.

关键词: 低能电子, 弹性散射, 径迹结构, MonteCarlo模拟, 辐射生物效应

Abstract: With a combination of mean cross section and Mott model,differential cross section,total cross section and angular distribution of electron elastic scattering in liquid water with energy below 10 keV are calculated and systematically compared with those of Rutherford model and experiment.Elastic scattering of low-energy electrons in liquid water is simulated.The method is reliable and can be applied conveniently to the simulation of track structure of low-energy electrons in liquid water.

Key words: low-energy electron, elastic scattering, track structure, Monte Carlo simulation, radiation biological effects
