Role of the Coulomb Potential in Compton Scattering
N. Melzer, M. Kircher, A. Pier +18
We report a fully differential study of ionization of the Ne L-shell by Compton scattering of 20 keV photons. We find two physical mechanisms which modify the Compton-electron emis…
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…
Selective Bond Breaking in CO Induced by Photoelectron Recoil
J. Weiherer, N. Melzer, M. Kircher +16
After core-ionization of CO, typically an Auger-Meitner decay takes place, leading to the formation of a dicationic molecule that may dissociate into CO and O. We demon…
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…
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 contrib…
