"Fast atom diffraction on crystal surfaces";
Vortrag: Seminar Institut für Allgemeine Physik (IAP), TU Wien; 31.03.2009.

Diffraction of particles scattered at surfaces was among the key experiments establishing the quantum wave nature of matter. Atoms being diffracted at crystal surfaces exhibit intriguing diffraction patterns, closely related to those visible in double-slit experiments, which have been carried out using particles as heavy as fullerenes. Scattering of keV atoms at surfaces has recently been shown to be a powerful tool to investigate the structure of surfaces. Even in environments which would strongly suggest the dominance of decohering effects (hot surfaces, phonon vibrations) quantum coherent scattering patterns remain visible. This is especially remarkable, as the de Broglie wavelength of scattered atoms in the keV range is as low as a few picometers.
