Dynamics of charge transfer and chemical reactions of doubly-charged ions at low collision energies

Abstract

Results of beam scattering studies on the dynamics of single charge transfer and chemical reactions of doubly-charged ions carried out in Prague are reviewed. Investigation of several atomic ion-atom charge transfer processes at collision energies 0·1-10 eV provides data on differential and relative total cross-sections of state-to-state processes. Populations of electronic and vibrational states of molecular product ions are obtained from experiments on molecular dication-atom and atomic ion (He²⁺)-molecule systems. Studies of chemical reactions of the dication CF²⁺ ₂ with D₂ show that Coulomb repulsion between the products (CF₂D⁺ + D⁺) governs the dynamics and energy partitioning.
