Breakdown of the spectator concept in low-electron-energy resonant decay processes
A. Mhamdi, J. Rist, D. Aslitürk +16
We suggest that low energy electrons, released by resonant decay processes, experience substantial scattering on the electron density of excited electrons, which remain a spectator…
Frustrated Coulomb explosion of small helium clusters
S. Kazandjian, J. Rist, M. Weller +17
Almost ten years ago, energetic neutral hydrogen atoms were detected after a strong-field double ionization of H. This process, called 'frustrated tunneling ionization', occurs…
Direct observation of interatomic Coulombic decay and subsequent ion-atom scattering in helium nanodroplets
F. Wiegandt, F. Trinter, K. Henrichs +13
We report on the experimental observation of interatomic Coulombic decay (ICD) in pure He nanoclusters of mean sizes between 5000 and 30000 and the subsequent scatt…
Absolute ion detection efficiencies of microchannel plates and funnel microchannel plates for multi-coincidence detection
K. Fehre, D. Trojanowskaja, J. Gatzke +11
Modern momentum imaging techniques allow for the investigation of complex molecules in the gas phase by detection of several fragment ions in coincidence. For these studies, it is…
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…
Separating Dipole and Quadrupole Contributions to Single-Photon Double Ionization
S. Grundmann, F. Trinter, A. W. Bray +12
We report on a kinematically complete measurement of double ionization of helium by a single 1100 eV circularly polarized photon. By exploiting dipole selection rules in the two-el…
