DYNAMICAL PROPERTIES OF DENSE ONE-COMPONENT PLASMAS WITHIN THE METHOD OF MOMENTS INTERPOLATION MODEL

Abstract

In this paper we present the results of investigation of dynamic characteristics
of dense one-component plasmas. In order to determine the dynamic structure factors (DSF) of
such systems, the interpolation self-consistent method of moments is employed, within which
the frequency moments are calculated as interpolations of the asymptotic relations for the exact
moments. The advantage of this method is the possibility of using approved fitting ratios for in-
ternal energy, which speeds up the computations. The obtained results, namely, the position, the
height of the DSF are in a good agreement with the computer modelling data in a broad range of
variation of the system parameters. Therefore, the conclusion is made that the interpolation self-
consistent moment method can be used to calculate dynamic structural factors and other dynam-
ic characteristics of a dense nonideal plasma.
Knowledge of DSF, in particular, allows calculating the dispersion of plasma waves, their
dissipation, as well as diagnosing the parameters of the medium under consideration.
