Radiation Chemistry of High-Energy Carbon, Neon, and Argon Ions: Hydroxyl Radical Yields

Chemical yields of H2O2 have been measured from aerated aqueous solutions of bromide and of formate irradiated at various pHs and solute concentrations with high-energy ions from the Berkeley Bevalac. Hydroxyl radical yields have been deduced from these data as a function of beam penetration into the solutions. By taking fragmentation of the primary ions into account, estimates of the instantaneous Gi OH values for the primary beams as a function of their energy have been made.
