Abstract

The simulation data [1,2] on the dynamic collision frequency (DCF) of hydrogen-like plasmas modelled with the Kelbg pseudopotential are treated within the theory of moments with local constraints. Additionally, the correlational sum rule which is the second power frequency moment of the external conductivity real part is taken into account to express the DCF in terms of the Nevanlinna parameter function. The validity of the suggetsed analytic form of the latter is tested against the simulation data, while the sum rules are calculated using the Kelbg potential and the Ornstein-Zernike hypernetted-chain equations.
