Ultrafast Charge Migration Induced by Inner-Shell Vacancy in Diiodomethane — •Maximilian Hollstein and Daniela Pfannkuche — Jungiusstraße 9, 20355 Hamburg

The ultrafast charge migration on the sub-femtosecond timescale following the inner-shell ionization of an iodine atom of the diiodomethane molecule is investigated theoretically using a truncated configuration interaction method. A significant charge redistribution induced by the inner-shell ionized iodine atom was found which takes place during the first 100 as. Except for fluctuations, the observed charge redistribution remains stationary on the femtosecond timescale. The importance of two-electron correlations within the charge redistribution process is studied by consideration of two-particle correlation functions.
