论文摘要
在不存在和存在圆形极化的单色电磁脉冲的情况下，我们分析了电子核子散射过程，其中假定核定核无旋转具有球形形状。我们通过使用Dirac-Volkov形式主义提供了差分横截面（DC）的理论计算。该研究论文旨在提供两种比较：我们首先在没有激光场的情况下将DC与相应的激光辅助DC进行比较。在电子 - 普罗替子和电子中子散射过程之间进行了第二个比较，以研究激光对这两个过程的影响。对于两个散射过程，已经讨论了有关激光场对DC和电构数的影响的结果。我们发现，当将激光场应用于两个过程时，DC会降低。另外，通过在电子普罗顿散射中提高入射电子能量也可以减少外形因子，但它增加了电子中子散射。此外，通过将激光场强度提高到$ 10^{8} \，v/cm $，两种散射情况的形式都没有变化。
In both absence and presence of a circularly polarized monochromatic electromagnetic pulse, we have analyzed the electron-nucleon scattering process, where the nucleon is assumed to be spinless with a spherical shape. We have provided the theoretical calculation of the differential cross section (DCS) by using the Dirac-Volkov formalism. This research paper aims to provide two comparisons: We first compare the DCS in the absence of the laser field with its corresponding laser-assisted DCS. A second comparison is made between the electron-proton and electron-neutron scattering processes to study the effect of the laser on both processes. The results obtained about the effect of the laser field on the DCS and the electric form factor have been discussed for both scattering processes. We have found that the DCS is reduced when the laser field is applied for both processes. In addition, the form factor is also decreased by raising the incident electron energy in electron-proton scattering, but it increases in electron-neutron scattering. Moreover, the form factors for both scattering situations are unchanged by raising the laser field strength up to $10^{8}\,V/cm$.
