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…
Auger decay of 1σg and 1σu hole states of N2 molecule: disentangling decay routes from coincidence measurements
S. K. Semenov, M. S. Schöffler, J. Titze +17
Results of the most sophisticated measurements in coincidence of the angular resolved K-shell photo- and Auger-electrons, and of two atomic ions produced by dissociation of N2 mole…
Fragmentation dynamics of CO23+ investigated by multiple electron capture in collisions with slow highly charged ions
N. Neumann, D. Hant, L. Ph. H. Schmidt +8
Fragmentation of highly charged molecular ions or clusters consisting of more than two atoms can proceed in an onestep synchronous manner where all bonds break simultaneously or se…
