Abstract
Self-consistent molecular-dynamics calculations of the charge of micron-siz e particles in a low-pressure gas-discharge plasma are performed. It is sho wn that charge exchange of ions on neutrals starts to affect the charge of dust particles at pressures corresponding to ion mean free paths much great er than the Debye radius. The computational results show that the potential of a particle depends nonmonotonically on the pressure and on the particle size. (C) 2000 MAIK "Nauka/Interperiodica".
