Space and Time Resolved Continuum Correlation in the Post-Collision Interaction of Core-Photoionized Neon*

We have used the COLTRIMS$^*$ technique to measure the momentum distribution of the photoelectron and the recoil ion produced by the core-photoionization of neon. Conservation of momentum allows us to determine the subsequent auger electron's momentum that is emitted when the Ne$^+$ relaxes to the Ne$^{2+}$ state. Momentum space plots of the electrons and the recoil ion are then used to resolve the three-body correlated post-collision interactions in space and time. Finally, classical calculations have been performed which corroborate our interpretation of the experimental results. \newline \newline $^*$R. Dorner, V. Mergel, O. Jagutzki, L. Spielberger, J.
