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…
