Abstract:

The nuclear spin lattice relaxation rate is measured in the temperature range 130 to 300 C, and is found to be expressed by the relation 1T sub 1 1.98 00082T x 1000sec. The two terms are attributable respectively to the quadrupole interaction and the magnetic hyperfine coupling. The latter is expected to be linear in the absolute temperature, and its magnitude a corresponds to the expected Korringa value. A model is constructed on the basis of fluctuations about a quasi-bcc lattice, and values of the rms field gradient q sub E 8.5 x 10 to the 24th powercu cm are related to the correlation times tau sub c 1.6 x 10 to the -13th power sec for self diffusion and the related step lengths delta r 0.38 A and the breadth of the x-ray diffraction peaks.
