Pressure fluctuations in nonideal nondegenerate plasma

Pressure fluctuations in equilibrium nonideal plasma are investigated by the method of classical molecular dynamics. Examples of plasma parameters at which the pressure-fluctuation distribution function is not normal but can be approximated by the sum of two normal distributions were found. The electron-ion interaction is described by the Coulomb potential cut-off at the depth of the potential well that is independent of the temperature and the particle density. The requirements on the choice of the interaction potential parameters and the number of particles in a calculation cell are discussed. The free and bound states are not separated in any way, which makes it possible to take into account successively the influence of density effects in the electron state spectrum on the thermodynamic properties.
