Charge Transfer Cross Sections for Multiply Charged Slow Ne, Ar, Kr and Xe Ions on Various Gas Targets : I. Rare Gas Targets

Observed charge transfer cross sections are compiled in an energy region from a few to tens keV for multiply charged Ne, Ar, Kr and Xe ions on rare gas targets, where projectile ions are produced by using an “ion-impact ion source” (IIIS). The values are compared with the results of other research workers

Charge Transfer Cross Sections for Multiply Charged Slow Ne, Ar, Kr and Xe Ions on Various Gas Targets : II. Molecular Gas Targets

Observed charge transfer cross sections are compiled, similarly to Part I, for multiply charged Ne, Ar, Kr and Xe ions on several molecular targets in an energy region from a few to tens keV. The projectiles are recoil ions produced by using our “ion-impact ion source” (IIIS). The values are compared with the results of other research workers

Isotope Effect on Charge Transfer Cross Sections of Slow 7Li+ Ions in Collisions with H2, HD, and D2 Molecules

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
