Résumé : The susceptibility of conduction electrons of dilute alloys is discussed including both electron–electron interactions and one‐electron impurity potentials. Adopting a two band model (s–d bands) a formal result is obtained for the partial susceptibilities, using the Green's function formalism and the Hartree‐Fock approximation. This solution is given in terms of a power series involving the Coulomb interaction and impurity parameters. An approximation is proposed, corresponding to a maximum exchange enhancement, for summing the power series, and an effective Coulomb scattering is obtained (for the fluctuations in the host) mediating the impurity scattering process.
