Studies of Electron-Ion Interactions using the CRYRING Heavy-Ion Storage Ring Facility

This report results from a contract tasking Stockholm University as follows: The Grantee will investigate the measurements of branching ratios in recombination of polyatomic molecular ions. It is proposed to study not only the rates of dissociative recombination of ions important for plasma-enhanced combustion but also the neutral product distributions. Deuterated molecules and peak fitting procedures will be applied to enhance the resolution. The proposed measurements will add greatly to the knowledge base in this unexplored field, yielding answers to the questions outlined above and serving as important inputs to the Air Force combustion models.
