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…
Probing Instantaneous Single-Molecule Chirality in the Planar Ground State of Formic Acid
D. Tsitsonis, M. Kircher, N. M. Novikovskiy +12
We experimentally demonstrate that individual molecules of formic acid are chiral even when they are in the vibronic ground state, which has a planar equilibrium structure. We ioni…
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…
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…
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…
Measuring the photoelectron emission delay in the molecular frame
Jonas Rist, Kim Klyssek, Nikolay M. Novikovskiy +22
If matter absorbs a photon of sufficient energy it emits an electron. The question of the duration of the emission process has intrigued scientists for decades. With the advent of…
