Viscosity of a multispecies plasma containing hydrogen and high-Z ions
  Materials containing hydrogen and high-Z ion species are used in a variety of high energy density physics (HED) applications, and it becomes increasingly important to investigate transport properties of these substances as they become fully-ionized multispecies plasmas. In particular, of significant practical interest, is the analysis of the plasma viscosity as it can determine stability and turbulence properties of the HED system. It has been pointed out by D. Ryutov [Phys. Plasmas 3, 4336 (1996)] that the presence of a substantial amount of hydrogen in a multispecies plasma can significantly enhance its viscosity. The present work reports on a detailed analysis of this effect and the accurate calculation of the corresponding viscosity coefficient.
