Abstract: | In this work, we studied the pair and triplet correlation functions in plasma composed of particles interacting via the Debye screening potential in the conditions of weak coupling parameter (Γ ≤ 1). The pair correlation functions are analysed numerically and compared to the hypernetted chains data, to the Monte Carlo data and to the results of Abramo and Tosi ??The triplet correlation functions are also analysed numerically and compared to the Kirkwood superposition approximation. At the end of our work, we give some applications to static structure factor and the dielectric constant. The results are well satisfactory. |
