Formation and Stability of High-Spin Alkali Clusters - Max-Born
... (b) With increasing cluster size the valence electron wave functions start to overlap sufficiently for electrons to migrate more or less freely from one atom to another and for that reason spin flips occur. The formally localized, spin-polarized electrons change into a delocalized, collective state. ...
