Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept. The occurrence of interference rests on the lack of which-way information and on the absence of decoherence mechanisms, which could scramble the wave fronts. Here, we report on the observation of two-center interference in the molecular-frame photoelectron momentum distribution upon ionization of the neon dimer by a strong laser field. Postselection of ions, which are measured in coincidence with electrons, allows choosing the symmetry of the residual ion, leading to observation of both, gerade and ungerade, types of interference.
波粒二象性是量子世界的固有特性。双缝实验被广泛用于理解这一基本概念的不同方面。干涉的发生取决于缺乏路径信息和没有退相干机制，这些机制可能会打乱波前。在这里，我们报告了在强激光场电离氖二聚体时，在分子框架光电离电子动量分布中观察到的双中心干涉。通过与电子同时测量的离子的后选择，可以选择残余离子的对称性，从而观察到两种类型的干涉，即正则和非正则。
