莫里哀的多重散射理论的电子和其他带电粒子在这里推导出数学上更简单的方式。微分散射定律仅通过一个参数,即屏蔽角χ a′进入理论,方程(二十一)、除了角度的绝对比例之外,角分布再次仅取决于单个参数B,等式(1):(二十二)、结果表明,B基本上只取决于散射箔的厚度(g/cm 2),而几乎与Z无关。
Moleère's theory of multiple scattering of electrons and other charged particles is here derived in a mathematically simpler way. The differential scattering law enters the theory only through a single parameter, the screening angle χ a′, Eq.(21). The angular distribution, except for the absolute scale of angles, depends again only on a single parameter b, Eq.(22). It is shown that b depends essentially only on the thickness of the scattering foil in g/cm 2, and is nearly independent of Z.
