Interaction of nano-sized particles in a dust-electron plasma

Dust-electron plasma, consisting of nano-sized particles and electrons emitted by them, is studied. It demonstrated that the particle charge can be suitably divided into two parts: own for each ``visible'' common neutralized background with assumption almost uniform spatial distribution electrons, deviates from uniformity only near dust particles. The visible both negative positive, while total positive. attraction likely charged possible, because interaction determined charges. equilibrium state between repulsion demonstrated.
