To the problem of influence of charging processes on the grain screening plasmas

Effects of charging processes on the effective screened field around a charged grain in plasma are studied within a linearized model of collisionless plasmas. It is shown that the above effects give rise to small contributions to the effective screened field predicted by the equilibrium linear screening theory within the rather wide range of plasma parameters typical of dusty plasmas. A considerable deviation from the linear screening theory is expected for larger grain sizes, of the order of the Debye length. The asymptotic behavior of effective potentials is considered
