摘要
我们报告了通过 20 keV 光子的康普顿散射对 Ne L 壳电离的全差分研究。我们发现了两种改变康普顿电子发射的物理机制。首先，我们观察到康普顿电子在其母核处的散射。其次，我们发现在接近零动量的电子动量分布中有一个明显的最大值，我们将其归因于库仑势对电子的聚焦。
Role of the Coulomb Potential in Compton Scattering
We report a fully differential study of ionization of the Ne L shell by Compton scattering of 20 keV photons. We find two physical mechanisms that modify the Compton-electron emission. Firstly, we observe scattering of the Compton electrons at their parent nucleus. Secondly, we find a distinct maximum in the electron momentum distribution close-to-zero momentum that we attribute to a focusing of the electrons by the Coulomb potential.
