Modeling of high-Z plasmas and opacities for radiation hydrodynamics simulations

  • A. Rickert
  • J. Meyer-Ter-Vehn


Within the framework of the collisional-radiative model a model is developed that describes state distribution and radiative opacities of dense plasmas that can be generated with laser or ion beams. It takes into account deviations from local thermodynamic equilibrium as well as non-ideality effects. Two-parameter atomic potentials are used and the Dirac equation is solved to obtain energies and wavefunctions. The influence of free electrons on the atomic potential is treated within the homogeneous free electron gas approximation. Results are presented for gold plasma including extinction coefficients forni=3·1020 cm−3,Te=100 eV and for photon energieshv=1-1500 eV.
