摘要：

The s-d- scattering amplitude, Γ, is calculated for the Takano-Ogawa Hamiltonian using ordinary Feynman diagrams. In ladder approximation, Γ diverges at the Kondo temperature. Self-consistently clothing the s-electron propagators moves the divergence to T=0, yielding Hamann's resistance result. © 1969.
