论文摘要
本文更新并补充了先前公布的总横截面和部分横截面的计算方法评估，这与对蒙特卡洛粒子传输中的光电效应进行建模有关。它检查了自上一篇论文发表以来已可以使用的计算方法，其中一些声称改进了先前的计算；它使用统计方法对它们进行测试，以针对收集的同一实验数据样本进行先前的评估。关于在EPDL97数据库中编码的预期目的，在上一篇论文中确定为最先进的计算方法，没有观察到统计学上的显着改进。与现有替代方案相比，一些最近的计算方法表现出重现实验测量的能力明显低。
This paper updates and complements a previously published evaluation of computational methods for total and partial cross sections, relevant to modeling the photoelectric effect in Monte Carlo particle transport. It examines calculation methods that have become available since the publication of the previous paper, some of which claim improvements over previous calculations; it tests them with statistical methods against the same sample of experimental data collected for the previous evaluation. No statistically significant improvements are observed with respect to the calculation method identified in the previous paper as the state of the art for the intended purpose, encoded in the EPDL97 data library. Some of the more recent computational methods exhibit significantly lower capability to reproduce experimental measurements than the existing alternatives.
