ABSTRACT
Natanson’s model {Zh. Tekh. Fiz., 30, 573 (1960) [English translation: Sov. Phys. Tech. Phys. 5, 538 (1960)]} for the collection of ions by aerosol particles is modified so that both the Coulomb force and the induced-dipole force are included for the case of attractive aerosol particles. Natanson included the induced-dipole force and the Coulomb force together only for the Coulomb force being repelling. The induced-dipole force increases ion collection rates by about a factor of 2 for the smallest aerosol particles. The results are applicable to the collection of both ions and electrons by noctilucent cloud particles and meteoritic dust in the mesosphere.
