Temporal Rearrangement of Electronic Densities in Slow Atomic Collisions

Electronic rearrangement in atomic interactions involve two very different time scales, for nuclear slow and electronic fast motions. This requires special care when one calculates solutions to the corresponding coupled differential equations. A method has been developed to treat the coupling of very different time scales, based on density operators in Liouville space. Its implementation in terms of density matrices, within an eikonalTDHF formulation, has allowed us to follow the time-evolution of atomic populations in ion-atom and ion-surface interactions.
