We present an improved version of the recently introduced formulas for the self-diffusion coefficient in the modified free volume theory of diffusion in simple fluids of particles interacting with Lennard-Jones potential. A suitable modification of the soft sphere levitation diameter and the replacement...

The average value for the mass of an atom in each atomic plane is given by the diffusion profile, solving Fick's diffusion equation for the superlattices. The value obtained here for the self-diffusion coefficient at 500 °C is 5.50×10-24 m2 s-1 and compares very well with previous res...
