We have investigated some Ag−Cd and Ag−Mg alloys within the KKR-CPA framework in order to give insights on their electronic properties. Notwithstanding Cd and Mg have different electronic configurations it appears that their effect on the pure Ag is quite the same. In fact measurements on their optical properties and Fermi surface indicate that most of the spectra and Fermi surface parameters are comparable. In the meantime it also appears that they cannot be classified as rigid band alloys. From the results we obtain it is possible to give sensible explanations to this peculiar behaviour in terms of the angularmomentum channels of the coherent scattering amplitude obtained within the KKR-CPA theory, the main conclusion being thats- andp-like states remain essentially free-electron-like, whiled-like states are very much perturbed by the alloying.
