Luminescence measurements of hyperthermal Xe + O and O + Xe collision systems.

Emission excitation cross sections are recorded for collisions between Xe + O and O + Xe over a collision energy range of approximately 2 to 900 eV in the center-of-mass (E) frame. Emissive products of the O + Xe reaction are examined in the 700-1000 nm optical range and include neutral atomic oxygen emissions and neutral xenon emissions. Atomic emission products of the O + Xe collision appear to have measureable cross sections near E = 14 eV and increase in intensity until about E = 60 eV where they remain approximately constant for the remainder of the measured collision energies.
