论文摘要
这项工作旨在从理论上研究在存在循环极化电磁场的情况下最初自旋偏振电子的电子蛋白散射。使用第一个诞生的近似值和Dirac-volkov态，用于借助型电子，我们借助自旋信度形式主义得出了差异横截面的分析表达。同时，采用了著名的自旋叶片和旋转非纤维差截面的概念。研究了电磁场对散射电子极化程度的影响，并检查了电子自旋极化的影响。我们发现，根据散射过程中的动能，电子的初始自旋可能会受到影响。这项工作是最近的一篇论文的延续，在该论文中，我们研究了在存在激光场的情况下的非极化电子普罗顿散射（Dahiri等，LaserPhys。Lett。18（2021）096001）。
This work aims to study theoretically the electron-proton scattering for initially spin-polarized electrons in the presence of a circularly polarized electromagnetic field. Using the first Born approximation and the Dirac-Volkov states for dressed electrons, we derive an analytic expression for the differential cross-section with the help of the spin-helicity formalism. Meanwhile, a well-known concept of spin-flip and spin non-flip differential cross sections is applied. The influence of the electromagnetic field on the degree of polarization of the scattered electron is investigated, and the effect of electron spin polarization is examined. We found that the initial spin of the electron can be affected depending on its kinetic energy during the scattering process. This work is a continuation of a recent paper in which we studied the unpolarized electron-proton scattering in the presence of a laser field (Dahiri, et al., Laser Phys. Lett. 18 (2021) 096001).
