Dynamics and Energy Relaxation of Formic Acid Dimers Following Inner Valence Ionization

J.X. Zhong Manis, Y.S. Wang, M.C. Rohan, S. Kumar et autres

We study gas-phase dissociation of the formic acid dimer dication as a model for DNA base-pair interactions after inner-valence 56 eV EUV ionization. Employing reaction microscopy, we measure the 3D momenta of electrons and fragment ions in coincidence to reconstruct channel-resolved electron …

Overview of the ASDEX Upgrade results

T. Pütterich, Felix Albrecht, Edoardo Alessi, Sehoon An et autres

Abstract After a 26-month vent ASDEX Upgrade (AUG) went back in operation with a newly designed upper W-divertor suitable for alternative divertor configurations (featuring in-vessel coils and cryo-pump). Parameter scans and an extensive set of measurements were obtained and their interpretation is …

Selective Bond Breaking in CO2+2 Induced by Photoelectron Recoil

J. Weiherer, N. Melzer, M. Kircher, A. Pier et autres

After core ionization of CO2, typically an Auger-Meitner decay takes place, leading to the formation of a dicationic molecule that may dissociate into CO+ and O+. We demonstrate experimentally that the recoil momentum of the photoelectron determines which of the two equivalent …
