摘要: 电子在固体中的弹性散射用Mot截面描述,提出一个简化的壳层电子激发计算方法将文献[5]中对电子非弹性散射的模拟拓展到重元素,用MonteCarlo方法模拟低能电子在Al、Cu、Au中的散射过程,计算的背散射系数、薄膜透射系数与实验一致.由此,计算得低能电子非弹性散射阻止本领并与Love、Rao-SahibWittry以及Joy的修正Bethe阻止本领作比较分析.

Abstract: Elastic scattering of Low-energy electron in solids is discribed with Mott cross-section, and a simplified calculation method on shell electron excitation is proposed.Monte Catlo simulation of low-energy electron scattering in Al, Cu, An have been proposed, the calculated backscattered coefficients, transmission coefficients are in good agreement with experiment results. Therefore, the stopping Power for low-energy electron are determined and comPared with results by Love, Rao-Sahib Wittry and Joy's modified Bethe equation.

Key words: Monte Carlo method, low-energy electron scattering, stopping power
