Molecular ions in dense interstellar clouds
Abstract
Ion kinetics in dense molecular clouds are considered. The molecular ion abundances are calculated using observational data on neutral molecules. H3+, CH3+, HCO+, C2H2+, H3O+, HS+, N2H+ are shown to be the most abundant. As far as ion-dust interactions are concerned, the only essential process is sticking of ions on the grain surface.
