Diffusivity of H in Ni

$$ D = D_0 \exp\left(-\frac{E_\mathrm{d}}{k_\mathrm{B}T}\right) $$

[In the above formula, the Boltzmann constant is expressed in \(\mathrm{eV\,K^{-1}}\).]

Comment

Comparison with Ebisuzaki (1967) results suggests mol in this work refers to mol (H2). Data provided by M. Lavrentiev (UKAEA, 2024) with permission from STEP.
