对莫里哀多次散射公式的修正

Correction to the Moliere's formula for multiple scattering

R. N. Lee, A. I. Milstein

摘要:

本文导出了对莫里哀多重散射公式的准经典修正。考虑的基础上的散射振幅,得到的第一个准经典修正考虑到任意的本地化,但不是球对称的潜力。与前导项不同,对莫里哀公式的校正不仅在组合$nL$(面密度)中包含目标密度$n$和厚度$L$。因此,这种校正可以称为体积密度校正。结果表明,即使对于高密度,体积密度校正也很小。这一结果解释了莫里哀公式的广泛适用范围。

英文摘要:

The quasiclassical correction to the Moliere's formula for multiple scattering is derived. The consideration is based on the scattering amplitude, obtained with the first quasiclassical correction taken into account for arbitrary localized but not spherically symmetric potential. Unlike the leading term, the correction to the Moliere's formula contains the target density $n$ and thickness $L$ not only in the combination $nL$ (areal density). Therefore, this correction can be reffered to as the bulk density correction. It turns out that the bulk density correction is small even for high density. This result explains the wide region of applicability of the Moliere's formula.
