Charge transfer of ground-state C+ , N+ , and O+ in N2 and H2

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 \ensuremath{\sim}5\ifmmode\times\else\texttimes\fi{}${10}^{7}$ cm ${\mathrm{sec}}^{\ensuremath{-}1}$.
