Abstract

The diffusion coefficients of sodium tracers in single crystals of pure sodium were measured as a function of temperature over a range of 20-41oC. The relation D=Do exp (-Q/RT) was found with Q 11,000 +/- 170 cal/mole and Do 0.313 +/- 0.018 cm2/sec. These values may be compared with Q=10,450 cal/mole and Do=0.242 cm2/sec. reported for polycrystalline sodium.
