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…
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…
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…
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…
Direct Experimental Access to the Nonadiabatic Initial Momentum Offset upon Tunnel Ionization
S. Eckart, K. Fehre, N. Eicke +11
We report on the non-adiabatic offset of the initial electron momentum distribution in the plane of polarization upon single ionization of argon by strong field tunneling and show…
