Here, we propose a new ultrafast chiral phenomenon exploiting recent advances in electron optics allowing access to the orbital angular momentum of free electrons. We show that strong-field ionization of a chiral target with a few-cycle linearly polarized 800 nm laser pulse yields photoelectron vortices, whose chirality reveals that <br> of the target, and we discuss the mechanism underlying this phenomenon. Our work opens new perspectives in recollision-based chiral imaging.本数据集包含用于发表论文《利用光电子涡旋实现分子手性超快成像》的绘图数据与绘图脚本。该论文的预印本可通过以下链接获取：https://arxiv.org/abs/2202.07289。数据集中附带readme.txt文件。<strong>作者：</strong><br>泽维尔·巴孔斯·普拉纳斯（Xavier Barcons Planas）、安德烈斯·奥多涅斯（Andrés Ordóñez）、马切伊·列文斯坦（Maciej Lewenstein）、安德鲁·斯蒂芬·马克斯韦尔（Andrew Stephen Maxwell）<strong>摘要：</strong>分子手性的超快成像是实现复杂生物相关分子中电子动力学成像与解析这一愿景的关键一步。本文借助近年来电子光学领域的研究突破，提出了一种全新的超快手性现象，该方法可获取自由电子的轨道角动量（orbital angular momentum）。研究表明，利用少周期线偏振800 nm激光脉冲对手性靶材进行强场电离（strong-field ionization），可产生光电子涡旋（photoelectron vortices），其手性可揭示靶材的<br>相关特性，本文还探讨了该现象的内在作用机制。本研究为基于重碰撞的手性成像领域开辟了全新的研究视角。
