Ion-charge-state chronoscopy of cascaded atomic Auger decay

Uphues T, Schultze M, Kling MF, et al. Ion-charge-state chronoscopy of cascaded atomic Auger decay. New Journal of Physics. 2008;10(2): 025009.It has recently been demonstrated that apart from the electron detection realized in the attosecond streak camera, also ion detection can be used for establishing extreme-ultraviolet pump) visible probe experiments, temporally resolving the dynamics of atomic inner-shell relaxation processes. We utilize this method for studying the Auger decay of krypton atoms following the creation of vacancy states in the 3d shell. It is shown that the electronic relaxation occurs through different pathways, each involving cascades of sequential steps which are followed in their native temporal succession
