title: Temperature-dependent pseudopotential between two pointlike electrical charges.
abstract: Pair distribution functions for particles electrically charged, at a temperature T expressed in terms of density matrices and corresponding pseudopotentials are studied, for distinguishable particles and for an electron pair. Expansions with respect to the separation distance and to a quantum parameter (approximately T(-1/2)) are carried out. Approximate expressions are derived in the limits of high and low temperatures.
