Electron Transfer in Intermetallic Compounds [PDF]

Proceedings of the National Academy of Sciences, 1950
In our discussions of the electronic structure of intermetallic compounds during the last three years brief mention has been made from time to time of the phenomenon of electron transfer [1-3]. The interpretation of the observed interatomic distances in many metallic phases seems to require the assumption that electron transfer has taken place; an ...
