Description:
Nature Physics 10, 207 (2014). doi:10.1038/nphys2880 Authors: Erik P. Månsson, Diego Guénot, Cord L. Arnold, David Kroon, Susan Kasper, J. Marcus Dahlström, Eva Lindroth, Anatoli S. Kheifets, Anne L’Huillier, Stacey L. Sorensen & Mathieu Gisselbrecht Double ionization following the absorption of a single photon is one of the most fundamental processes requiring interaction between electrons. Information about this interaction is usually obtained by detecting emitted particles without access to real-time dynamics. Here, attosecond light pulses, electron wave packet interferometry and coincidence techniques are combined to measure electron emission times in double ionization of xenon using single ionization as a clock, providing unique insight into the two-electron ejection mechanism. Access to many-particle dynamics in real time is of fundamental importance for understanding processes induced by electron correlation in atomic, molecular and more complex systems.
