论文摘要
我们研究了基状态氦的激光辅助单XUV光子双电离。通过求解完整的六维时间依赖性schr {Ö} dinger方程，我们研究了相关性和角度分布。关节能量和角度分布中的讨论揭示了在存在弱激光场的情况下，奇数甚至奇偶校验双电离过程中的竞争。可以通过激光参数调整两个光电子之间的发射角。我们描述了激光场如何增强和/或启用双电离的背对背和并排发射。
We investigate the laser-assisted single XUV photon double ionization of ground state helium. By solving full six-dimensional time-dependent schr{ö}dinger equation, we study the correlation and angular distribution. The discussion in joint energy and angular distributions reveals the competition in odd and even parity double ionization processes in the presence of weak laser field. The emission angle between two photoelectrons can be adjusted by the laser parameters. We depicts how the laser field enhance and/or enable the back-to-back and side-by-side emission of double ionization.
