A mechanism for diffusion in solid metals is proposed in which the rate-limiting atom movements occur within small regions of disorder in the crystal. The disordered regions consist, on the average, of 12 to 14 atoms which have relaxed inward around a lattice vacancy, and have an energy content abou
## Abstract The biexponential relaxation behavior of the sodium nucleus affects the accuracy of quantitative measurement of __in vivo__ tissue sodium concentration (TSC). Theoretical analysis and __in vivo__ experimental results are used to demonstrate the extent of the large bias in the measured T
