Interatomic Coulombic decay following electronic excitations — •Kirill Gokhberg — Physikalisch-Chemisches Institut, Heidelberg University, Germany

Ultrafast non-radiative decay of excited electronic states embedded into an environment by interatomic Coulombic decay or ICD mechanism has been a topic of extensive theoretical and experimental work. An interesting and comparatively unexplored area of the ICD research is the role of an environment in the decay of resonantly excited atoms and molecules. Theoretical calculations show that the ICD lifetimes of such states range from a few hundred to a few tens femtoseconds. These large ICD rates imply that the excited state dynamics observed in isolated system will be drastically modified by the environment. We illustrate this on examples of molecular photodissociation, and multiple ionisation of rare gas clusters in strong fields.
