摘要
A semiclassical version of the pseudoatom molecular dynamics method is used to calculate the coefficients of dynamic viscosity and ion self-diffusion of a warm and moderately heated dense plasma of a number of chemical elements, which are of interest for the high-energy-density physics, the solution of a number of applied geophysical and planetology problems, and a comparison with the calculated data of other authors. The effects caused by the Coulomb interaction in a medium and the quantum properties of the electronic subsystem of plasma are taken into account. Analytical approximations are proposed for the coefficients of viscosity and ion self-diffusion, and they can be used to simulate the dynamics of dense ionized matter for describing experiments in the high-energy-density physics.
