Due to the difficulty in producing atomic oxygen in the laboratory, there are very few reported measurements of scattering cross sections with an atomic oxygen target.$\sp{2-6}$ We have undertaken an experimental program designed to measure absolute differential cross sections for various collision processes involving atomic oxygen. The oxygen atoms are produced through dissociation of O$\sb2$ in a microwave discharge, producing a target of atomic and molecular oxygen whose densities are inferred from measurements with an electron impact time of flight mass spectrometer.63 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
