Zusammenfassung:The Knight shift and spin-lattice relaxation time of Nb were measured temp. from room temp. to 1700 deg K. A quantitative interpretation of T1T data is presented, and a K- Chi analysis to determine the various contributions to the magnetic susceptibility. The activation energy for diffusion, observed in the relaxation data, is also determined.16 refs.--AA
