The diffusion of 68Ge in single crystals of high-purity (over 99.99% pure) Ni has been measured using the sectioning technique. The plot of log D versus 1/T is straight from 939 to 1675K, over 61/2 orders of magnitude in D, with parameters D0=2.10+or-0.47 cm2 s-1, Q=2.74+or-0.03 eV (264+or-3 kJ mol-1). The data suggest a low Ge-vacancy binding enthalpy for Ni.
