Auger line shape in alloys

A theory for Auger line shapes in alloys is presented and applied to dilute alloys with "free-electron"-like and "noble-metal"-like hosts. For noble-metal-like hosts it is shown that anomalous impurity Auger line shapes can be expected. The theory is developed for degenerate d st...

Description
Summary:A theory for Auger line shapes in alloys is presented and applied to dilute alloys with "free-electron"-like and "noble-metal"-like hosts. For noble-metal-like hosts it is shown that anomalous impurity Auger line shapes can be expected. The theory is developed for degenerate d states, for which the conditions under which the atomic-aplit two-hole terms can be treated independently are determined. The Auger line shape for more concentrated alloys (Cu--Cd) is discussed qualitatively and is shown to yield information about the nearest-neighbor surroundings. 30 ref.--AA
