RADIAL DISTRIBUTION FUNCTIONS FOR A HYDROGENOUS PLASMA IN EQUILIBRIUM

Radial distribution functions gab(r) for a dense hydrogenous plasma (ni=ne=1018 electrons/cc) are obtained near the ionization temperature by solving the Percus-Yevick equation and a modified Percus-Yevick equation. The effective interparticle potentials used were obtained previously by a direct evaluation of their corresponding two-particle Slater sums, and include the Heisenberg quantal effect, but not the statistical quantal effect. The iterative solution of the equations, even using a variety of numerical procedures, is found to break down when the ionization falls appreciably. © 1969 The American Physical Society.
