Four-body reaction dynamics:: Complete correlated fragment measurement of the dissociative photodetachment dynamics of O-8 -: art. no. 033005

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 O8- 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.
