ResumoIn most of the recent works on the lowtemperature anomalies due to the sod interaction between conduction electrons and magnetic impurities in metals, the ordinary scattering by the impurity potential was ignored from the outset.Only a few authors, including Suhl,l) Fischer2) and Kondo,3) investigated its effect on this problem.It was stressed by Suhl 4 ) that the coupling between the potential and the exchange scattering plays an essential role to understand the recent experiments on eu-Fe') and Au-V 6 ) dilute alloys.In a recent paper, Kondo 3 ) studied this problem by means of the Green's function method.n,B)Following Hamann,B) he derived an integral equation for Llt(w) =t(w)to(w), and solved it in a perturbational way.
