Intermediate-coupling calculation of atomic spectra from hot plasma

Theory and experiment for ultrahigh pressure shock Hugoniots

“…HOPE [9,14] is a self-consistent Dirac-Slater average atom model and it can account for detailed electronic configurations. In HOPE the boundary conditions for the bound states are given at the ion-sphere radius requiring that either the wave function or its derivative be zero, thus giving a rough estimate for the widths of the electronic bands.…”

Electron scattering in hot/warm plasmas

“…The aim of this paper is twofold; to present high temperature calculations where radiation energy transport is important and to see the extent electron transport competes with radiation transport and to present low temperature calculations where experimental data are available. As was stated before, the computations use the self-consistent potentials and other EOS data as inputs from a self-consistent Dirac-Slater model that was published before [1,2,3,4], the main part of this paper is the computation of scattering states, phase shifts and structure factors. The author does not intend to present an unnecessary set of redundant figures, so we illustrate the physics details for aluminum only, which are quite similar for the other two elements.…”

“…The key element is the electron momentum transfer cross section that enters into the formulas for both the electrical and thermal conductivities. The potential in which the electrons scatter is a basic element and that is taken as an input from the author's temperature and density dependent self-consistent model for the plasma [1], that was also used for the computation of radiative properties [2,3,4]. For the computation of the electrical resistivity we use the Ziman formula [5,6,7], whereas for the thermal conductivity we adopt the method of L. Mestel [8,9].…”

Analysis of atomic physics models for gold plasmas in local thermodynamic equilibrium

“…Following the procedure reported by Goldberg et al (1986), each configuration is created by promoting and denoting electrons in turn to the atom that is obtained from the fictitious average ion using the nearest integer values of the electron populations in each shell. Following the procedure reported by Goldberg et al (1986), each configuration is created by promoting and denoting electrons in turn to the atom that is obtained from the fictitious average ion using the nearest integer values of the electron populations in each shell.…”

“…We do not follow the same procedure of Goldberg et al (1986) for obtaining the atomic data of each configuration. We recompute the energy levels, wave functions, and transition probabilities for each configuration, solving the radial Dirac equation.…”
