The feasibility of an atomicversion of Young's double slit experiment for matter waves in ion-atom collisions was first discussed theoreticallyby Tuan and Gerjuoy in 1960[1]. They studied capture processes in collisions of protons with H2 and suggestedthat diffraction of the protons from the two atomic centers of the molecule could lead to interference effects. Suchinterference effects are more difficult to observe in ionization processes, since there the final state of the collisioninvolves at least three unbound particles. The experimental observation of this process is particularly challengingbecause the determination of the phase angle in such processes is not straightforward.展开更多
