The diffusion of V was measured, at 6 temperatures. The pre-exponential factor and activation energy were evaluated by means of least-squares fitting of the experimental data to the Arrhenius equation, and it was found that the results could be described by:

D (m2/s) = 3.59 x 10-5 exp[-309.07(kJ)/RT]
