The self-diffusion mechanism in sodium is investigated by means of NMR techniques in the temperature range 150-280 K. The temperature dependence of the measured correlation factor confirms the simultaneous migration of mono- and divacancies as the major cause for the curvature of the Arrhenius plot. © 1980.
