Double-slit photoelectron interference in strong-field ionization of the neon dimer
Maksim Kunitski, Nicolas Eicke, Pia Huber +13
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental c…
Determination of the He-He, Ne-Ne, Ar-Ar, and H interaction potential by wave function imaging
S. Zeller, M. Kunitski, J. Voigtsberger +10
We report on a direct method to measure the internuclear potential energy curve of diatomic systems. A COLTRIMS reaction microscope was used to measure the squares of the vibration…
Electron localization in dissociating by retroaction of a photoelectron onto its source
M. Waitz, D. Aslitürk, N. Wechselberger +19
We investigate the dissociation of into a proton and a after single ionization with photons of an energy close to the threshold. We find that the and the …
Imaging the He quantum halo state using a free electron laser
S. Zeller, M. Kunitski, J. Voigtsberger +24
We report on coulomb explosion imaging of the wavefunction of the quantum halo system He. Each atom of this system is ionized by tunnelionization in a femto second laser pulse…
Observation of the Efimov state of the helium trimer
Maksim Kunitski, Stefan Zeller, Jörg Voigtsberger +9
Quantum theory dictates that upon weakening the two-body interaction in a three-body system, an infinite number of three-body bound states of a huge spatial extent emerge just befo…
Agreement at last: an experimental and theoretical study on the single ionization of helium by fast proton impact
H. Gassert, O. Chuluunbaatar, M. Waitz +20
Even though ion/atom-collision is a mature field of atomic physics great discrepancies between experiment and theoretical calculations are still common. Here we present experimenta…
Interatomic-Coulombic-decay-induced recapture of photoelectrons in helium dimers
P. Burzynski, F. Trinter, J. B. Williams +17
We investigate the onset of photoionization shakeup induced interatomic Coulombic decay (ICD) in He2 at the He+*(n = 2) threshold by detecting two He+ ions in coincidence. We find…
Ion impact induced Interatomic Coulombic Decay in neon and argon dimers
H. -K. Kim, H. Gassert, M. S. Schöffler +16
We investigate the contribution of Interatomic Coulombic Decay induced by ion impact in neon and argon dimers (Ne and Ar) to the production of low energy electrons. Our exp…
Vibrationally Resolved Decay Width of Interatomic Coulombic Decay in HeNe
F. Trinter, J. B. Williams, M. Weller +17
We investigate the ionization of HeNe from below the He 1s3p excitation to the He ionization threshold. We observe HeNe ions with an enhancement by more than a factor of 60 whe…
A measurement of the evolution of Interatomic Coulombic Decay in the time domain
F. Trinter, J. B. Williams, M. Weller +17
During the last 15 years a novel decay mechanism of excited atoms has been discovered and investigated. This so called ''Interatomic Coulombic Decay'' (ICD) involves the chemical e…
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…
