Monocrystalline Hg-saturated material was studied at 473 to 616K. It was found that the diffusivity data could be described by:

D (cm2/s) = 5.23 x 10-9 exp[-0.19(eV)/kT]

for fast diffusion via an interstitial mechanism, and by:

D (cm2/s) = 1.26 x 10-10 exp[-0.14(eV)/kT]

for slow diffusion via a lattice-site substitution mechanism.
