Single-electron charge transfer in collisions of CF 2 ++ with Ar and Ne at collision energies 3–5 eV

Abstract

Non-dissociative, single-electron charge transfer processes between the dication CF2++ and Ar and Ne were investigated in crossed beam scattering experiments at collision energies of 3.0 and 4.55eV (c.m.). The reaction with Ar produces CF2+ in its ground state and, to a smaller extent, in the excited CF2+(2Пu) state. The reaction with Ne occurs only with an excited state of CF2++ lying about 4.4 eV above the ground state and present in a small amount in the reactant dication beam; its molecular product is CF2+ in the ground state.
