Ionic Reactions in Gaseous Monosilane

Abstract
The ions SiH3+, Si2H+, Si2H2+, Si2H3+, Si2H4+, and Si2H5+ appear as products in ionized SiH4. All are formed from the attack of SiH2+ ions on SiH4 molecules. The specific reaction rates for the formation of these ions are, in units of cubic centimeters per moleule·second×1010, respectively, 1.7, 0.13, 0.67, 0.39, 1.1, and 0.068.
