Abstract
Mathematical, particularly, asymptotic properties of the random-phase approximation, Mermin approximation,
and extended Mermin-type approximation of the coupled plasma dielectric function are analyzed within the
method of moments. These models are generalized for two-component plasmas. Some drawbacks and advantages
of the above models are pointed out. The two-component plasma stopping power is shown to be enhanced with
respect to that of the electron fluid.
