Time correlation functions for electron dynamics near a positively charged radiator are described by a mean field kinetic theory that is exact in the short time limit. The important case of the electric field autocorrelation function is examined and the dependence on radiator charge number is shown to be dominated by the bound states of the electron-ion potential. A very simple practical model is proposed and shown to be accurate over a wide range of electron-ion coupling conditions. The model is expected to be useful for more complex conditions confronted in recent theories for line shapes.
