Optical Emission from Ion-Atom and Ion Molecule Interactions

Reactions of the rare gases, Rg, (Rg = Ar, Kr, Xe) with helium molecular ions, argon molecular ions and argon ions producing excitation have been investigated. All excitation is accompanied by the transfer of translational into internal energy via charge-transfer or collisional excitation reactions....

Description
Summary:Reactions of the rare gases, Rg, (Rg = Ar, Kr, Xe) with helium molecular ions, argon molecular ions and argon ions producing excitation have been investigated. All excitation is accompanied by the transfer of translational into internal energy via charge-transfer or collisional excitation reactions. Collisions of the argon atomic and molecular ions are efficient in exciting the resonant radiation in the RgI spectrum. Kinetic energy thresholds for several of these reactions are reported. The symmetric system Xe ion/Xe has been studied with respect to production of Xe ion neutral atomic resonance radiation. The effects of the electronic state of the reacting xenon ions are discussed and possible reaction mechanisms are proposed. (Author)
