摘要：

Using a highly accurate method of analytic continuation, we calculated the dynamic susceptibility and NMR relaxation rate 1/T1 of magnetic (Anderson or Kondo) impurities over the entire range T << T-kappa to T >> T-kappa. We find that the susceptibility and NMR relaxation rate are universal functions when properly scaled and that the NMR relaxation rate is directly proportional to the universal Kondo resistivity.
