ABSTRACT

The pair correlation function (PCF) in a non-degenerated plasma, containing multi-species of electric charges (electrons, positive and negative ions and impurities) are calculated in a Multi-Component Plasma (MCP) model. The method stands on the use of the statistical mechanics under the mean-field theory approach where the screening and the quantum effects have been taken into account. The coupled system of the obtained nonlinear integral equations (NIES) governing the pair correlation functions are solved numerically in three-dimensional space with three different methods: Fixed Point Method (FPM), Verlet Method (VM) and Finite Difference Method (FDM). These methods generally give the same results which are in a good agreement with those obtained by the molecular dynamics simulation (MD).
