Control of Ionization of Molecules on Both Attosecond and Ångström Dimensions – CIMBAAD

Submission summary

In CIMBAAD, we propose to explore a new and promising research direction opened by attosecond science, namely the study of molecular photoionization at “ultimate” attosecond timescale and Ångström lengthscale. Our purpose is to investigate how the electronic excitation initiating the photoionization process may be localized either spatially or spectrally in order to control the ionization event and the corresponding electron hole dynamics that may lead ultimately to molecular fragmentation. Our experimental and theoretical studies will first be dedicated to small molecules and hydrocarbons for which sophisticated theoretical approaches and advanced experimental techniques can be developed. We will then make the first move towards the investigation of larger polyatomic nanometric structures such as fullerenes that are so far entirely unexplored in this regime of interaction. By combining techniques with unprecedented spatial and temporal resolutions, we will be able to study and potentially to control on their natural scales some of the most basic processes of physics, chemistry and biology: electron excitation, migration and ejection. Conversely, these processes also serve as very accurate probes of the systems under investigation. The combination of the experimental and theoretical expertises of CEA, ILM and LCPMR in attoscience will be a strong asset for this challenging goal and for the development of the expanding field of attosecond molecular physics.
