A new approach to the determination of charge transfer in metal alloys

Abstract An account is given of recent progress in studying charge transfer in alloys by focusing attention on the atomic core potential and evaluating environmentally induced changes in this quantity by measuring shifts in the initial and final state Auger parameters. The importance of the information on the local physical structure of alloys that can be obtained from the EXAFS technique will also be discussed. Recent work on AuMg and AuZn alloys and the CuPd alloy system will be described.
