Abstract
Measurements of nonresonant charge transfer between atomic ions and atoms have been made in a drift-tube—mass-spectrometer apparatus as a function of (drift field/gas pressure) at 295 K. At the charge-transfer coefficients are: /sec, , . For + Hg and + Hg, is ≤ , while for + Ne and + Ar, is ≤ /sec. Little dependence of and on ion energy is found up to mean energies of eV. Comparison of the measured rates with available theories suggests an inability to predict the moderately slow reaction rates.
