State-to-State Ion-Molecule Reaction Dynamics at Thermal Energies
Abstract
Our application for the DURIP grant was motivated by our need for an intense, narrow band-width tunable ultraviolet pulsed laser source to conduct experiments under our current research grant (AFOSR-89-0264). The laser system we purchased from Spectra-Physics, using the DURIP grant, delivers over 30 milliJoules per pulse of tunable light at 280 nanometer with a bandwidth as small as .08 wave numbers. We have employed this new laser system to measure ion state distributions using high resolution photoelectron kinetic energy spectroscopy. This laser system is also being used to conduct two color ionize/ probe experiments, which permit the study of collisional relaxation and charge transfer. Using the DURIP grant we also plan to upgrade our WEX-1 wavelength extension unit to accommodate a (2,5-dibiphenylyloxazole) crystal. This upgrade will extend the wavelength range over which we can generate greater than 3 milliJoules per pulse to wavelengths as short as 200 nanometers. (jg)
