  dielectric function
The calculations are based on the exactly solved model of a sharp metal/electrolyte interface, the model of a Born sphere for the ion, and the three-mode approximation for the dielectric function of the solvent.
      
Parameters of the analytical expression used for the dielectric function ε(k) of the solvent are selected so as to reproduce the results of calculations of the ε(k) function obtained by a molecular dynamics method.
      
The complex dielectric function of the films was determined from the experimental data by dispersion analysis of the reflection spectra.
      
This effect is related to the fact that a contribution to the dielectric function of slow ions, determining the scattering amplitude, depends on both spatial and frequency dispersion.
      
The k-dependent semiclassical dielectric function is employed instead of the Lindhard-Mermin expression.

We study the interaction of the swift C 60 ion\|clusters with solids. The dynamic interacting forces acting on the individual ions in the cluster are derived based on the linear\|response dielectric theory with the PLA dielectric function, and a set of equations describing the motion of the individual ions is obtained. It has been shown that by solving the equations of the motion, the wake effects of the dynamic interactions result in the strong asymmetric structures of the high\|velocity C 60 clusters, i.e., the leading ions in the cluster explode very fast, while the trailing ions in the cluster almost remain in stable states.
