The distribution of activation energies $\ensuremath{\Delta}$ for classical over-the-barrier hopping is computed for a model amorphous metal. The spread in $\ensuremath{\Delta}$ is determined by the variation in equilibrium-site and saddle-point sizes for the assumed model of dense random packing (DRP) of soft spheres. The size distribution is related to the radial distribution function in a manner which reproduces recent numerical results for the interstitials in DRP models. Size (distance… CONTINUE READING
