Nuclear Magnetic Resonance Experiment on Metal Cadmium. II

The spin-lattice relaxation time, T 1 and the spin-spin relaxation time, T 2 , of the resonance line in metal cadmium were measured by use of a nuclear magnetic resonance technique. The contribution of p -character in the conduction electron to the relaxation was estimated. The line width was measured at a temperature between the room temperature and 250°C. It was shown that the exchange broadening between unlike spins underwent a motional narrowing. The inverse line width or spin-spin relaxation time, T 2 , was interpreted in terms of the lattice diffusion theory. These analyses yielded for the coefficient of self-diffusion D the value 0.05 cm 2 /sec exp (-17.6 kcal/mol-RT).
