Single photon double ionization of the helium dimer
T. Havermeier, T. Jahnke, K. Kreidi +16
We show that a single photon can ionize the two helium atoms of the helium dimer in a distance up to 10 °A. The energy sharing among the electrons, the angular distributions of the…
Interatomic Coulombic Decay following Photoionization of the Helium Dimer: Observation of Vibrational Structure
T. Havermeier, T. Jahnke, K. Kreidi +15
Using synchrotron radiation we simultaneously ionize and excite one helium atom of a helium dimer (He_2) in a shakeup process. The populated states of the dimer ion (i.e. He^[*+](n…
Coherent reflection of He atom beams from rough surfaces at near-grazing incidence
Bum Suk Zhao, H. Christian Schewe, Gerard Meijer +1
We here report coherent reflection of thermal He atom beams from various microscopically rough surfaces at grazing incidence. For a sufficiently small normal component of the…
Emerging beam resonances in atom diffraction from a reflection grating
Bum Suk Zhao, Gerard Meijer, Wieland Schöllkopf
We report on the observation of emerging beam resonances, well known as Rayleigh-Wood anomalies and threshold resonances in photon and electron diffraction, respectively, in an ato…
