The key goal of the project to improve our understanding of fundamental gas-surface and gas-phase reactioninteraction dynamics that relate directly to orbital and sub-orbital spacecraft or missile missions of direct relevance to the U.S. Air Force was fulfilled. However, the details of the work performed differed from those proposed. Scientific curiosity, experimental opportunities, and discussions with the Program Manager Dr. Michael Berman led to a modification of some of the detailed objectives of this project. Seminal data were obtained on the hyperthermal reactions of ground-state O3P with H2, D2, and small hydrocarbons methane, ethane, and propane. The hyperthermal atomic oxygen source was confirmed to contain atomic oxygen in its ground O3P state by a combination experimenttheory study of the reaction, OH2-OHH, where Prof. George Schatz of Northwestern University conducted the theoretical calculations. A similar study on the reaction of the hyperthermal beam with CH4 showed that the molecular oxygen component of the beam is in its ground state.
