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

説明

<jats:title>Abstract</jats:title><jats:p>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, <jats:italic>gerade</jats:italic> and <jats:italic>ungerade</jats:italic>, types of interference.</jats:p>
