论文摘要
我们采用R-Matrix采用时间依赖性方法来研究F $^ - $的Attsond Antcular条纹。使用这种不含远距离库仑相互作用的负离子，我们阐明了短距离电子相关效应在attoclock方案中的作用。通过解决多电体时间依赖性的施罗宾格方程的解决方案，我们旨在使用多电极目标和单电子理论方法弥合实验之间的差距。尽管结合电位的性质短，但我们观察到光电子动量分布中的显着负偏移角。我们表明，偏移角度对残留F原子的原子结构描述很敏感。我们还研究了共旋转电子的响应，并观察到它们的发射中的角度分离。
We employ the R-matrix with time-dependence method to study attosecond angular streaking of F$^-$. Using this negative ion, free of long-range Coulomb interactions, we elucidate the role of short-range electron correlation effects in an attoclock scheme. Through solution of the multielectron time-dependent Schrodinger equation, we aim to bridge the gap between experiments using multielectron targets, and one-electron theoretical approaches. We observe significant negative offset angles in the photoelectron momentum distributions, despite the short-range nature of the binding potential. We show that the offset angle is sensitive to the atomic structure description of the residual F atom. We also investigate the response of co- and counter-rotating electrons, and observe an angular separation in their emission.
