Abstract:

Progress is described in a three-year program of research supported by AFOSR under the High-Energy-Density-Matter HEDM initiative. A laser-crossed molecular beam apparatus was constructed which is equipped to probe unique high- energy excited states by 1 directly detecting anion photoproducts of charge- transfer intermediate excited states 2 determining internal state distributions following photoionization of high-energy intermediates by time-of- flight photoelectron spectroscopy and 3 characterizing ion-fragment disturbutions by time-of-flight mass spectroscopy. This instrument was employed in combination with a second, quadrupole molecular beam system to complete a set of experiments exploring structural and dynamical properties of high-energy matter. AFOSR supported experiments have detected anions arising from energetic charge-transfer configurations of monomeric HC1. Additional work on the same molecule, has probed intermediate-state effects on ion-fragment branching rations, and, by double-resonance, characterized the dynamics of rotationally state selected spin-orbit autoionization.
