Evidence of Wave-Particle Duality in Slow/Intermediate Electron Transfer CollisionsHYBRID

Wave-particle duality is an inherent property of quantum mechanics. In the optical Young double-slit experiment, each slit acts as a coherent source of secondary waves, and interference patterns appear on a screen. In a quantum-mechanical double-slit experiment, diatomic molecules resemble the optical double-slit, in which the bond length acts as the slit separation. For electron transfer collisions, the variations observed in the molecular-axis orientation-dependent cross-sections are caused by the interference between the scattering amplitudes of two capture paths close to either of the centers. On the other hand, the state-selective scattering angle differential cross-sections exhibit oscillatory patterns similar to optical Fraunhofer diffraction, where the range of impact parameters defines the aperture radius. Over the last few decades, evidence for wave-particle duality has been investigated in heavy-particle-induced interference and matter-wave diffraction to bridge the gap between classical optics and heavy-ion collisions. The first part of this talk will discuss the two-center interference phenomenon in slow- and intermediate-velocity electron-transfer collisions. The second part will focus on Fraunhofer-type matter-wave diffraction in highly charged ion-atom/molecule collisions in the strongly perturbative regime.
