标题： Double-slit photoelectron interference in strong-field ionization of the neon dimer

摘要： 波粒二象性是量子世界的一种固有特性。 双缝实验经常被用来理解这一基本概念的不同方面。 干涉现象的发生取决于缺乏路径信息以及不存在可能扰乱波前的退相干机制。 在本文中，我们报告了在强激光场电离氖二聚体时，在分子框架下的光电子动量分布中观察到的双中心干涉现象。 对与电子同时测量的离子进行后选择，使得可以选择连续态电子波函数的对称性，从而观察到既包括正宇称也包括负宇称的干涉类型。 显示英文摘要

摘要： 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. In this letter, 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 were measured in coincidence with electrons, allowed choosing the symmetry of the continuum electronic wave function, leading to observation of both, gerade and ungerade, types of interference.
