Alternating-current conductivity measurements were carried out at 0.5 to 20kHz. The diffusivity of 110mAg was determined by using microtome and scintillation counting techniques. The diffusion results, for temperatures of between 100 and 260C, could be described by the expression:

D (cm2/s) = 0.00023 exp[-0.128(eV)/kT]

From these, and other results, it was deduced that the Haven ratio at temperatures of between 100 and 140C was equal to 0.9.
