The diffusion coefficient of tracer amounts of Au/sup 198/ in gamma U is described by an Arrhenius-type equation: D = 4.86 x 10 cm/sup -3/sec exp(-30,400 cal/mol/RT). The values of D/sub 0/ and the activation energy are close to those for self-diffusion in gamma U, indicating that the low activation energy for self- diffusion is due to a general weakness of the lattice rather than to easy compressibility of the U atom.
