Impact of Mie Scattering on Charging of Dust Grains

In this paper Mie scattering of light by dust particles having MRN power law distribution of size has been incorporated in the formulation of the kinetics of an illuminated complex plasma; the number and energy balance of the constituent species are considered. Unlike usual case (when Mie scattering ignored) it is seen that the charge on a particle is not proportional to the radius and that for certain sets of parameters the smaller particles are negatively charged while the larger particles, carry positive charge.
