摘要：

The Cu-63 spin-lattice relaxation rate 1/T-1 in UCu3.5Pd1.5 has been determined at frequencies 38 MHz less than or equal to v(0) less than or equal to 101 MHz and for temperatures 0.4 K less than or equal to T less than or equal to 100 K. UCu3.5Pd1.5 was one of the first compounds revealing non-Fermi-liquid behavior which was explained in terms of a distribution of Kondo temperatures T-K. In contrast to the broad distribution of single Kondo impurity temperatures T-K, which accounted for the bulk susceptibility X(H,T), such a distribution P(T-K) does not describe the results of our Cu-63-NMR experiments performed at high applied external fields H-0 greater than or equal to 51 kOe.
