Abstract
A theory of the charge-density oscillation around resonant scatterers is presented which explains the recent experimental results on the anomalous charge perturbation around transition-metal impurities in Al and Cu. Its application to the Kondo effect suggests a crucial test for the existence of the Kondo resonance, and shows that available NMR data rule out the validity of the Kondo model for -transition-metal alloys, while further experiments are proposed to answer this question in the case of Cu-based alloys.
