Total cross sections for charge transfer for ${\mathrm{F}}^{+}$ in ${\mathrm{H}}_2$, ${\mathrm{N}}_2$, He, Ne, and Ar

Absolute measurements are reported of the total cross section ${\sigma }_{10}$ for charge transfer of ${\mathrm{F}}^{+}$ in ${\mathrm{H}}_2$, ${\mathrm{N}}_2$, He, Ne, and Ar in the energy range from 14 to 100 keV. The measured cross sections are in qualitative agreement with theory. However, it is observed that the slopes of the cross section versus velocity for velocities above the maximum in the cross sections differ for molecular and atomic targets used in this study.
