Notes:
Absolute total cross sections have been measured for collisions of Cl−, Br−, and I− with HCl, DCl, and HBr for projectile energies ranging from 5 to 300 eV. The processes investigated include reactive scattering and electron detachment. The reactive scattering cross sections exhibit considerable isotope effects and the collisional dynamics are discussed within the framework of a spectator-stripping model which involves proton or deuteron abstraction. The results for the I− projectile are substantially different from those for Cl− and Br−; this difference is suggested to be related to the relative stability of the molecular anion, HI−.
