Abstract
The temperature-dependent impurity susceptibility for the symmetric Anderson Hamiltonian is discussed for all physically relevant values of its parameters U (the Coulomb correlation energy) and Γ (the d-level width). For U>πΓ, the results, for temperatures less than U/10kB, map onto those of the spin-½ Kondo Hamiltonian with an effective exchange constant given by ρ Jeff=-8Γ/πU. At higher temperatures the results show the formation of the local moment from the free orbital.
