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.

我们将探讨结合分子状态在强场光电离世中的作用。将收集由H2形成的照片电子的精确动量分布，并将其与最近理论预测的光电子分布进行比较。类似数据将记录在分子氧中，该分子氧与H2具有许多相似之处，但缺乏长期结合的Rydberg状态。该研究包括搜索电子动量空间分布异常的迹象，以及用于光电子签名中分子比对的对准和复兴的迹象。目的是提供一个可靠的数据库，在精确的情况下是前所未有的，对分子的强景响应的当前和未来的理论可以测试。希望在我们最近在氩气电离的情况下达到的一定程度。
