From: Non-ergodic dissociative valence double ionization of SF6

Upper panel: electron pair spectra based on threefold coincidence events for the main charge retaining channels and for production of F+ as proxy for all charge separation channels. Lower panel: electron pair spectra based on fourfold coincidence events (two electrons, two ions) showing the main charge separation channels, all displayed on the double ionization energy scale. The intensities for some of the spectra have been scaled by the factors given in the figure, and are displaced vertically for clarity. The error bars represent the statistical uncertainty of the coincidence counts.
