AI总结:

本研究通过圆偏振双色激光场对手性分子进行强场电离,发现相对螺旋度影响光电子圆二色性,且PECD随亚周期释放时间调制,提出基于手性初始态电子的启发式模型解释该现象。

摘要:

我们报道了在圆偏振双色激光场中S-和R-环氧丙烷的强场电离。我们发现两个单色激光场的相对螺旋度影响光电子圆二色性(PECD)。此外,我们观察到PECD作为电子亚周期释放时间的函数被调制。我们的实验观察被一个基于手性初始态中电子的启发式模型成功描述,这些电子被激光场选择性地释放,并在隧穿后与非手性库仑势相互作用。

英文摘要:

We report on strong field ionization of S- and R-propylene oxide in circularly polarized two-color laser fields. We find that the relative helicity of the two single color laser fields affects the photoelectron circular dichroism (PECD). Further, we observe that PECD is modulated as a function of the sub-cycle release time of the electron. Our experimental observations are successfully described by a heuristic model based on electrons in chiral initial states, which are selectively liberated by the laser field and, after tunneling, interact with an achiral Coulomb potential.
