Polarization of Dusty “Quasiatoms” in Low-Density Plasma

A model of the polarization dust particles with trapped ions in an external electric field is presented. It based on self-consistent solution integral balance equation for ion density and Poisson potential. shown that, a low collisional regime, form spread shell maximum located at some distance from thecharged particle proportional to Debye length. The estimated polarizability dusty "quasiatoms" very high anddepends strength due ionization ions. With increase electricfield, "quasiatom" loses their far orbits ionization. radius ionic becomes smaller, coefficient decreases.
