Final state alignment for electron transfer

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.
