Formation of Sodium Ions by Charge Transfer

Abstract

Cross sections have been measured in the energy range 1–500 eV for the charge transfer of several ions with neutral sodium. The ions studied are O⁺, N⁺, ${\mathrm{N}}_2^{+},$ NO⁺, ${\mathrm{O}}_2^{+},$ H₂O⁺, H₃O⁺, N₂O⁺, and Na⁺. The magnitude of these cross sections can be related to the availability of reaction paths which have a small internal energy defect. The smaller the energy defect the larger the cross section. Where possible the measured cross sections have been extrapolated to thermal energy. Comparison is made with other experiments.
