Abstract
Relation between the plasma responses on singular and regular initial perturbations is established. Time scaling is introduced that separates periods for which eigen-oscillations (Landau solutions) are dominant from those, where ballistic modes prevail. The enhanced role of the ballistic modes for a plasma initially free of a perturbation field is demonstrated, too, including the phenomenon of plasma waves echoes.
