The diffusion-elastic effect was applied to the measurement of H diffusivity. The simplest initial and boundary conditions for the solution of Fick's equation were assumed. The diffusivity at 30C was equal to 2.28 x 10-9cm2/s. This value seemed to agree with published data, to within experimental error.
