PECD and PICD effects in chiral and achiral molecules (A01)

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: since 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 328961117

The goal of this project is to gain a deeper understanding of circular dichroism (CD) effect upon the absorption of a single high energetic photon. To this end we will use a COLTRIMS reaction microscope that detects emitted electrons and ions in coincidence to study CD effects in unexpected constellations: Can a photoelectron CD (PECD) be observed in an initially achiral molecule, thus a system where it shouldn’t show up? How is PECD affected by secondary electron emission (Auger decay)? Is a CD effect observable on the ion left behind?
