In the temperature region 780 to 940 °C the diffusion of 59Fe in silver single crystals is investigated. The diffusion coefficient, D = 1.90 exp (− 49.36/RT) cm2/s, agrees with the earlier work of Mullen. The calculations of the correlation factor fi for the AgFe system using Mullen's results and from the model of LeClaire and the Tm-model, further support the vacancy mechanism to be operative in this system.
