Interatomare korrelierte Zerfallsprozesse in dotierten Helium-NanoTröpfchen - Sondierung heterogener Nanosysteme mit EUV-Strahlung
Zusammenfassung der Projektergebnisse
This project was scientifically very productive, and the cost-benefit ratio was excellent. This was mainly due to the efficient way of carrying out experiments in a concerted effort with a team of experienced researchers using proven techniques. In addition, the particular system of pure and doped He nanodroplets had not been studied much in the extreme-ultraviolet regime and not at all using electron-ion coincidence detection aside from the host and the PI's own preliminary work. It turned out that He nanodroplets feature very interesting and unusual electronic and nuclear dynamics when being electronically excited or ionized. Many fundamental secondary processes like ICD, ETMD, elastic and inelastic electron scattering, droplet-induced electron-ion recombination, electronic relaxation were investigated. This research complies with the current trend of shifting focus on ICD and related phenomena in condensed phase systems rather than isolated small molecules. Thus, nearly all of the goals as well as additional achievements were reached, except for the study of pump-probe dynamics of dopants in He nanodroplets by combining optical laser pulses to EUV pulses from Elettra synchrotron radiation. Some of these experiments will be carried out in near future experiments by the PI at ELI-beamlines.
