Abstract
Charge transfer cross sections of 7Li+ ions in collisions with H2, HD, and D2 molecules have been measured in the energy range from 1.4 to 4.0 keV using the growth rate method. Significant differences in the charge transfer cross sections between collisions of 7Li+ ions with H2 and HD, and with H2 and D2 molecules, the so-called target isotope effect, are observed at collision energies from 1.4 to 2.4 keV. The observed charge transfer cross section ratios of σ (HD)/σ (H2) and σ (D2)/σ (H2) are found to be approximately 0.7 at 1.4 keV. They are gradually increasing, and finally approaching unity at energies above 2.4 keV.
