Abstract
The pair interaction potential of charged particles in a dense two-component plasmas, which takes into account quantum-mechanical effects, was obtained on the basis of the comparison of the quantum-mechanical Slater sum with the classical Boltzmann factor. The equations issued from this comparison were solved numerically and the spline approximation of these numerical results gives the interpolation formula for the pair interaction potential. The potential is valid in the temperature region of 104 < K < T < 108K and density region of 10 21 cm -3 < n≤ 10 24 cm -3 It was shown that at high temperatures and densities the results have a good agreement with well known models of Deutsch and Kelbg.
