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…

X-ray Coulomb explosion imaging reveals role of molecular structure in internal conversion

Till Jahnke, Sebastian Mai, Surjendu Bhattacharyya +26

Molecular photoabsorption results in an electronic excitation/ionization which couples to the rearrangement of the nuclei. The resulting intertwined change of nuclear and electroni…

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…

Photoelectron circular dichroism of O 1-photoelectrons of uniaxially oriented trifluoromethyloxirane: Energy dependence and sensitivity to molecular configuration

G. Nalin, K. Fehre, F. Trinter +25

The photoelectron circular dichroism (PECD) of the O 1s-photoelectrons of trifluoromethyloxirane(TFMOx) is studied experimentally and theoretically for different photoelectron kine…

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…

Magnetic fields alter tunneling in strong-field ionization

A. Hartung, S. Eckart, S. Brennecke +16

When a strong laser pulse induces the ionization of an atom, momentum conservation dictates that the absorbed photons transfer their momentum to the electron and its pa…

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…

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…

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…

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…
