Abstract

This paper presents cross sections for collisions of neutral atoms/molecules with a charged spherical nanoparticle, which is the source of the dipole potential. The accuracy of the orbital limited motion (OLM) approximation is estimated. It is shown that simple analytical formulas for the atoms/molecules and heat fluxes, obtained in the OLM approximation, give an error of not more than 15% and are applicable in all reasonable range of nanoparticles and weakly ionized plasma parameters.
