Abstract:

This instrumentation grant was used to design and fabricate an intense neutral particle beamline for use in gas-surface collision experiments. The three-fold differentially pumped beamline is being used in conjunction with a new inelastic electron-surface scattering spectrometer in order to extend our studies of surface reactivity and gas-surface collision phenomena into many areas. New capabilities include the ability to examine surface reaction kinetics occurring on surfaces as opposed to monitoring volatile reaction products, encounters between optically excited and translationally selected molecules and surfaces, gaseous condensation, and surface photochemistry. Future surface oxidation studies involving atomic reactants and radicals will also be possible pending construction of appropriate atomicmolecular nozzle beam sources. The instrumentation assembled under the auspices of this grant has directly enhanced research efforts.
