Using a highly accurate method of analytic continuation, we calculated the dynamic susceptibility and NMR relaxation rate 1/{ital T}{sub 1} of magnetic (Anderson or Kondo) impurities over the {ital entire} range {ital T}{much lt}{ital T}{sub {ital K}} to {ital T}{much gt}{ital T}{sub {ital K}}. 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.
