angular momentum作用下氢原子场电离引出电子的横动量不对称性

Transverse momentum asymmetry of the extracted electron in field ionization of a Hydrogen Atom with angular momentum

Xavier Artru, Essma Redouane-Salah

摘要:

本文研究了在静态电场中激发的氢原子的隧穿电离,其中电子在被引出之前具有垂直于电场E的轨道角动量L。逃逸电子在E交叉方向上有一个非零的平均横向速度<vT><L>。这种不对称性类似于横向极化夸克碎裂成强子的柯林斯效应。此外,线性斯塔克效应使<L>系统<vT>在时间上振荡.非对称度的计算在E中的最大横向的初始状态的领先阶<L>。这种不对称性的观察条件进行了讨论。

英文摘要:

The tunneling ionization of a hydrogen atom excited in the presence of a static electric field is investigated for the case where, before being extracted, the electron has an orbital angular momentum L perpendicular to the field E. The escaping electron has a nonzero mean transverse velocity <vT> in the direction of E cross <L>. This asymmetry is similar to the Collins effect in the fragmentation into hadrons of a transversely polarized quark. In addition, the linear Stark effect make <L> and <vT> oscillate in time. The degree of asymmetry is calculated at leading order in E for an initial state of maximum transverse <L>. The conditions for the observation of this asymmetry are discussed.
