我们对镁原子电子轰击电离的全微分截面进行了计算。本文将三种理论近似，即瞬态紧耦合、三体畸变波和畸变波 Born 近似与实验进行了比较。将显示不对称和对称共面几何形状的 Mg 基态电离结果。还将显示由线偏振激光激发的状态电离的结果，该激光产生垂直于激光束方向并平行于线偏振方向排列的电荷云。将在散射平面以及垂直于入射光束方向的平面中对几种不同对准角度的理论和实验结果进行比较。
We have performed calculations of the fully differential cross sections for electron-impact ionization of magnesium atoms. Three theoretical approximations, the time-dependent close coupling, the three-body distorted wave, and the distorted wave Born approximation, are compared with experiment in this article. Results will be shown for ionization of theground state of Mg for both asymmetric and symmetric coplanar geometries. Results will also be shown for ionization of thestate which has been excited by a linearly polarized laser which produces a charge cloud aligned perpendicular to the laser beam direction and parallel to the linear polarization. Theoretical and experimental results will be compared for several different alignment angles, both in the scattering plane as well as in the plane perpendicular to the incident beam direction.
