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…
Recoil-Induced Asymmetry of Nondipole Molecular Frame Photoelectron Angular Distributions in the Hard X-ray Regime
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…
Observation of Photoion Backward Emission in Photoionization of He and N2
Sven Grundmann, Max Kircher, Isabel Vela-Perez +14
We experimentally investigate the effects of the linear photon momentum on the momentum distributions of photoions and photoelectrons generated in one-photon ionization in an energ…
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…
