Using a radio‐frequency field pulse technique which enables measurement of slow atomic diffusion by means of nuclear magnetic resonance we have obtained, for nominally 6–9's pure Al, an activation energy for self‐diffusion of 28.75 ± 0.8 kcal∕mole. Data was obtained over a range of 5 decades in atomic jump rate (240°C to 550°C) and joins smoothly with other diffusion coefficient measurements at the extremes. © 1967 The American Institute of Physics
