NMR of Co^'<59> diluted in Cu metal has been studied in the temperature range from 1.1 to 4.2°K. The Knight shift of Co^<59> is large and positive (5.2±0.2%). It is independent of the concentration of Co and the temperature. The observed Knight shift is separated into d-orbital part and d-spin part using the susceptibility data. The value of T_1T is 20±5 msec°K in our experimental region. By using the Korringa type relation between the Knight shift and T_1T, the main part of the Knight shift and the relaxation is shown to be attributed to the orbital interaction. The dominant part of the line width of Co^<59> which is proportional both to the external magnetic field and the concentration of Co arsies from the inhomogeneous polarization of the impurity spins.
