The diffusive behavior of 82Br was studied. The results could be described by:

250-570C:     D (cm2/s) = 2.0 x 10-8 exp[-0.34(eV)/kT]

570-700C:     D (cm2/s) = 6.0 x 10-3 exp[-1.30(eV)/kT]

The best linear fits to the solute diffusion data ([336] to [347]) yield:

Ar: Ln[Do] = 0.77E – 13 (R2 = 0.98); Br: Ln[Do] = 0.49E – 18.3 (R2 = 0.88);

He: Ln[Do] = 1.17E – 15.9 (R2 = 0.58)
