Final state alignment for electron transfer

Abstract

The final state integral alignment for the electron transfer process is investigated in the keV energy range. Experimentally, polarization analysed photons from the Li I - transition are detected in coincidence with scattered Li neutrals in the 1-25 keV impact energy range. Over most of this range, we find good agreement with 26- and 35-state atomic orbital (AO) basis coupled-channel calculations, as well as with 28-state molecular orbital (MO) basis predictions. Limits of validity of the two theoretical approaches are also discussed in terms of the predicted state-to-state transfer cross sections.
