Electron lifetimes in silver alloys

Abstract

De Haas-van Alphen measurements of impurity scattering in dilute AgAu, AgSn, AgCd and AgGe alloys have been made. A number of different orbits on the Fermi surface have been investigated and maps of the scattering probability have been constructed. These maps have been interpreted, using impurity phase shifts obtained from the electrical resistivity in terms of the s, p and d electron charge density over the silver Fermi surface.
