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…
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…
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…
