摘要:

本文综述了原子结合能在通用蒙特卡罗系统中的应用。这些参数的各种汇编进行了评估,其准确性估计相对于实验数据。它们对与蒙特卡罗粒子输运相关的物理量的影响被突出显示:X射线荧光发射,电子和质子电离截面,以及康普顿散射中的多普勒展宽。由于不同的结合能的影响进行量化相对于实验数据。分析结果为结合能的选择提供了定量依据,以优化实验用例中蒙特卡罗模拟的准确性。讨论了处理这些参数的软件设计和改进蒙特卡罗模拟数据库的建议。

英文摘要:

A survey of atomic binding energies used by general purpose Monte Carlo systems is reported. Various compilations of these parameters have been evaluated; their accuracy is estimated with respect to experimental data. Their effects on physics quantities relevant to Monte Carlo particle transport are highlighted: X-ray fluorescence emission, electron and proton ionization cross sections, and Doppler broadening in Compton scattering. The effects due to different binding energies are quantified with respect to experimental data. The results of the analysis provide quantitative ground for the selection of binding energies to optimize the accuracy of Monte Carlo simulation in experimental use cases. Recommendations on software design dealing with these parameters and on the improvement of data libraries for Monte Carlo simulation are discussed.
