Abstract

The wipe-out number for the first order quadrupole effect in the NMR of matrix nuclei was measured in dilute Cu-Ag, Cu-Ga and Cu-Ge alloys in order to study the asymptotic behavior of the charge density oscillation around different non-transitional metal impurities. The measured values of the wipe-out numbers were compared with the predictions from Friedel's theory by using the phase shifts calculated by Blatt, Kohn-Vosko, Alfred-Van Ostenburg. "Empirical" phase shifts (η0, η1, η2) for the Cu-Zn, Cu-Ga and Cu-Ge alloys were determined on the basis of Faber-Ziman diagrams. The values of the experimentally determined first order wipe-out number, the residual resistivity, and the Knight shift measured on the smelts, were described by these phase shifts.
