Experimental Observation of Non-Exponential Auger-Meitner Decay of Inner-Shell-Excited CO
M. Weller, G. Kastirke, J. Rist +10
Electronically excited atoms or molecules may deexcite by emission of a secondary electron through an Auger-Meitner decay. This deexcitation process is typically considered to be e…
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…
Fourfold Differential Photoelectron Circular Dichroism
K. Fehre, N. M. Novikovskiy, S. Grundmann +28
We report on a joint experimental and theoretical study of photoelectron circular dichroism (PECD) in methyloxirane. By detecting O 1s-photoelectrons in coincidence with fragment i…
A new route for enantio-sensitive structure determination by photoelectron scattering on molecules in the gas phase
K. Fehre, N. M. Novikovskiy, S. Grundmann +28
X-ray as well as electron diffraction are powerful tools for structure determination of molecules. Studies on randomly oriented molecules in the gas-phase address cases in which mo…
Strong Differential Photoion Circular Dichroism in Strong-Field Ionization of Chiral Molecules
K. Fehre, S. Eckart, M. Kunitski +14
We investigate the differential ionization probability of chiral molecules in the strong field regime as a function of the helicity of the incident light. To this end, we analyze t…
Zeptosecond Birth Time Delay in Molecular Photoionization
Sven Grundmann, Daniel Trabert, Kilian Fehre +11
Photoionization is one of the fundamental light-matter interaction processes in which the absorption of a photon launches the escape of an electron. The time scale of the process p…
Revealing the Two-Electron Cusp in the Ground States of He and H2 via Quasifree Double Photoionization
S. Grundmann, V. Serov, F. Trinter +15
We report on kinematically complete measurements and ab initio non-perturbative calculations of double ionization of He and H2 by a single 800 eV circularly polarized photon. We co…
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…
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…
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…
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…
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…
