Ion and Electron Momentum Distributions from Single and Double Ionization of Helium Induced by Compton Scattering
M. Kircher, F. Trinter, S. Grundmann +18
We present the momentum distributions of the nucleus and of the electrons from double ionization of the helium atom by Compton scattering of photons with keV. We find that…

The photoelectron circular dichroism (PECD) of the O 1s-photoelectrons of trifluoromethyloxirane(TFMOx) is studied experimentally and theoretically for different photoelectron kine…
Photon-momentum-induced molecular dynamics in photoionization of N at keV
M. Kircher, J. Rist, F. Trinter +16
We investigate K-shell ionization of N at 40 keV photon energy. Using a COLTRIMS reaction microscope we determine the vector momenta of the photoelectron, the Auger electron an…

M. Kircher, J. Rist, F. Trinter +15
We investigate angular emission distributions of the 1s-photoelectrons of N ionized by linearly polarized synchrotron radiation at keV. As expected, nondipole contribu…
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…

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…
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…
Imaging the square of the correlated two-electron wave function of a hydrogen molecule
M. Waitz, R. Y. Bello, D. Metz +21
The toolbox for imaging molecules is well-equipped today. Some techniques visualize the geometrical structure, others the electron density or electron orbitals. Molecules are many-…
Stereochemical configuration and selective excitation of the chiral molecule halothane
Martin Pitzer, Gregor Kastirke, Phillip Burzynski +12
X-ray single-photon ionization and fragmentation of the chiral molecule halothane (CHBrClCF) from a racemic mixture have been investigated using the COLTRIMS (Cold Target R…
Observation of enhanced chiral asymmetries in the inner-shell photoionization of uniaxially oriented methyloxirane enantiomers
Maurice Tia, Martin Pitzer, Gregor Kastirke +38
Most large molecules are chiral in their structure: they exist as two enantiomers, which are mirror images of each other. Whereas the rovibronic sublevels of two enantiomers are al…
Two-particle interference of electron pairs on a molecular level
M. Waitz, D. Metz, J. Lower +19
We investigate the photo-doubleionization of molecules with 400 eV photons. We find that the emitted electrons do not show any sign of two-center interference fringes in thei…
