Reactive and charge transfer processes in electronically inelastic collisions between ground state cadmium(II) diiodide molecules and lithium ions in the 0.10–4.00 keV energy range by crossed molecular beams

Abstract

Charge transfer processes leading to different excited states of lithium atoms in the collision system CdI 2 ( 1 Σ g + ) + Li + ( 1 S g ) have been studied by crossed molecular beams techniques. Absolute emission cross-sections for the different exit channels have been measured as a function of the collision energy in the 0.10–4.00 keV energy range. Also the excitation function for the collision induced dissociation process leading to Cd (5 3P 1) has been obtained. Ab initio structure calculations performed at the second order Möller–Plesset level furnish a picture of the non-adiabatic effects for some of the electron transfers experimentally observed.
