Four-body reaction dynamics: complete correlated fragment measurement of the dissociative photodetachment dynamics of O(-)(8).

The four-body dissociative photodetachment (DPD) dynamics of O-8 were studied using photoelectron photofragment coincidence (PPC) spectroscopy. All four neutral photofragments were measured in coincidence with the photodetached electron, yielding a five-body kinematically complete experiment. Velocity and angular correlations for DPD of O(-)(8) are presented and compared to those for O(-)(6). The DPD dynamics and energetics of O(-)(8).are found to be similar to those of O-4 and O-6 implying that the additional solvating O(2) molecules act essentially as spectators, but exhibit inequivalent kinematic behavior implying asymmetric solvation.
