We discuss the usefulness of the independent-particle model to describe charge-transfer processes. We consider, as a benchmark case, avoided crossing transitions in two-electron systems, described by means of the Landau-Zener-Stueckelberg model. It is shown that the independent-particle model, with an equivalentelectron interpretation of the one-electron transition probabilities, reproduces single-electron transition probabilities for a wide range of physical situations.
