Abstract

The equation of state and species concentrations of a hot neutral gas of neutrons, protons, electrons, positrons, and muons are determined in the temperature range 5× $10^{10}$ -5× $10^{11}$ °K and density range 5× $10^{10}$ - $10^{14}$ g/ ${cm}^{3}$ . The gas is considered to be in local thermal and chemical equilibrium under the effect of weak and strong interactions. A virial expansion is constructed to include second-order statistical and dynamical terms, the latter through experimental nucleon-nucleon scattering phase shifts. Decreases in pressure and increases in electron number densities are found to be quite modest.
