Radiation effects in solvated matter are of great interest, since many aspects of them are still poorly understood and better knowledge can be beneficial for radiation protection and radiation therapy. Especially, relaxation processes between core-shell ionized solvated samples and surrounding water molecules are worth investigating. They are called interatomic/intermolecular processes that dissipate deposited energy and charge to neighboring atoms and molecules. Here, the final states of initially ionized targets can be less charged compared to the case that the target is an isolated system where Auger decay most likely occurs. For a better understanding of complex decay processes of irradiated atoms and molecules in solution, Auger cascade processes, that create highly charged final states, and its suppression via competitive interatomic/intermolecular decay processes, of core ionized iodide anion in aqueous solution was investigated. Results are obtained by a combination of liquid microjet technique and multielectron coincidence spectroscopy.
