Kinetic Theory of the Interdiffusion Coefficient in Dense Plasmas
Ionic diffusion in dense plasma mixtures has been of interest recently for a number of reasons. In astrophysics, diffusion plays a central role in understanding the distribution of heavy elements in the atmospheres of White Dwarf stars.1 The performance of multi-layer x-ray mirrors should be affected by diffusion, and the evaporation rate of metal “chunks” injected into the fuel of an ICF capsule by hydrodynamic instabilities is controlled by the diffusion coefficient.
