Dissociative photoionisation of molecules probed by triple coincidence; Double time-of-flight techniques

Abstract

Two novel experiments producing three-dimensional histograms of time-of-flight correlations have recently been performed at the Daresbury Synchrotron Radiation Source. In the first, the two photoions from the double ionisation of SF6 were detected; in the second, the photoelectron and the O+ ion from the predissociation of O2+. This technique allows a visual insight into the details of dissociative photoionisation which has not been available previously.
