K.A. Hanold, M.C. Garner and R.E. Continetti, "Photoelectron-Photofragment Angular Correlation and Energy Partitioning in Dissociative Photodetachment.", Phys. Rev. Lett. 77, 3335-3338 (1996). |
| Measurements of photoelectron-photofragment angular correlation and energy partitioning in the dissociative photodetachment of O4- (O4- + hv --> O2+O2+e-) at 532 nm are reported. Using photofragment translational energy and photoelectron spectroscopy in coincidence, vibrationally resolved product translational energy distributions and a pronounced angular correlation between the photoelectron and photofragment recoil directions are observed. These results provide insights into the molecule-fixed photoelectron angular distribution of a negative ion and structural information on O4- in the gas phase. |
