Intense-field molecular ionization, for extended test of theory

我们将探索束缚分子态在强场光致电离中的作用。由H2形成的光电子的精确动量分布将被收集起来，并与最近的理论预测进行比较。类似的数据将被记录在分子氧中，分子氧与氢有许多相似之处，但缺乏长寿命的束缚里德堡态。这项研究包括在电子动量的空间分布中寻找异常的迹象，以及在光电子信号中寻找分子排列和恢复排列的迹象。目标是提供一个可靠的数据库，其精度前所未有，可以用来检验当前和未来关于分子强场响应的理论。我们希望达成某种程度的协议，就像我们最近在Ar中的强场电离情况下所展示的那样。

We will explore the role of bound molecular states in strong field photoionization. Precise momentum distributions of photo-electrons formed from H2 will be gathered and compared with those predicted by recent theory. Analogous data will be recorded in molecular oxygen, which shares many similarities with H2 but which lacks long-lived bound Rydberg states. The study includes a search for signs of anomalities in the spatial distribution of electron momenta, and for signs of alignment and revival of molecular alignment in the photoelectron signature.The goal is to provide a reliable database, unprecedented in precision, against which current and future theories on the strong-field response of molecules can be tested. The hope is to reach a level of agreement as we recently demonstrated in the case of strong-field ionization in argon.
