Charge transfer of ground-state ${\mathrm{C}}^{+}$, ${\mathrm{N}}^{+}$, and ${\mathrm{O}}^{+}$ in ${\mathrm{N}}_2$ and ${\mathrm{H}}_2$

The single-electron charge-transfer cross sections for ground-state ${\mathrm{C}}^{+}$, ${\mathrm{N}}^{+}$, and ${\mathrm{O}}^{+}$ ions colliding with ${\mathrm{N}}_2$ and ${\mathrm{H}}_2$ are reported. Comparison with results from a mixed-state beam (i.e., an ion beam containing both ground-state and metastable-state ions) of ${\mathrm{C}}^{+}$ and ${\mathrm{O}}^{+}$ ions indicate that single-electron charge-transfer cross sections are equal for ground-state and metastable-state ${\mathrm{C}}^{+}$ and ${\mathrm{O}}^{+}$ ions for velocities greater than ∼5×${10}^7$ cm ${\sec }^{-1\mathrm{}}$.
