Abstract

We present calculations of cross sections for electron- and positron-scattering from atomic beryllium over a wide range of incident energies from the first inelastic thresholds to 5000 eV. We use model potentials that have been shown to be reliable over a wide energy range in previous studies. The present work includes the total, integrated elastic, momentum transfer, and differential cross sections. In addition, we have found several critical minima in the differential cross sections for both electron and positron scattering.

原子铍对电子和正电子的散射

摘要

我们介绍了在从第一非弹性阈值到5000 eV的宽入射能量范围内，原子铍对电子和正电子散射的截面计算。我们使用的模型势在以前的研究中已经证明在广泛的能量范围内是可靠的。目前的工作包括总的，综合的弹性，动量传递和微分截面。此外，我们在电子和正电子散射的微分截面中发现了几个临界极小值。
