Electron transfer processes in collisions of ions and
molecules at low keV energies
Abstract:
The talk will give an overview of our recent results on collisions of
charged ions with atoms and molecules. Systems relevant to fusion plasma,
astronomy or hadron therapy are focused upon, namely the electron
capture and electronic excitation by proton impact on H2, D2, HD,
and various hydrocarbon molecules. The electronic structure and
dynamics of positive H2O+ and H3O+ intermediate ions are also briefly
discussed.
The theoretical framework builds on the MRD-CI method to determine
the electronic states and their respective non-adiabatic couplings
and uses the electronic-state close-coupling method to obtain
the cross sections for the above processes. The importance of
vibrational, steric and isomer effects is demonstrated.
We conclude with a very brief summary of our research interest
in quantum dot physics and econphysics, seeking for a possible
research cooperation.
