Charge transfer between ground-state N²⁺ and H₂, N₂, and CO at electron-volt energies

The charge-transfer rate coefficients for reactions of N²⁺(2s²2p ²P^o) with H₂, N₂, and CO are measured using ion storage. A cylindrical rf ion trap was used to store N²⁺ ions produced by laser ablation of a solid titanium nitride target. The rate coefficients were derived from the decay rate of the ion signal. The rate coefficients for the above three reactions are 3.38(0.35)×10^-11 cm³ s^-1 at T_equiv=2.9×10³ K, 2.10(0.18)×10^-9 cm³ s^-1 at T_equiv=1.3×10⁴ K, and 3.37(0.29)×10^-9 cm³ s^-1 at T_equiv=1.3×10⁴ K, respectively. No theoretical or other experimental values are available at this energy range.
