Charge Transfer Cross Sections of Slow Multiply Charged Neon Ions in Collisions with Noble Gas Atoms

Single and multiple charge transfer cross sections for Neq+ (q = 2 - 6) ions were measured in collisions with Ne, Ar, Kr, and Xe atoms at 2q keV. Quintuple charge transfer cross sections σ6,1 were derived for the Ne6+ + Ne, Ar, and Xe collisions. In Ne atoms, the double, triple, and quadruple charge transfer of Ne2+, Ne3+, and Ne4+ ions, respectively, represent so-called symmetric resonant charge transfer processes. The present data for these collisions are in good accordance with the previous data. The scaling properties of the total, single, and multiple charge transfer cross sections were examined, and it was found that the double, triple, and quadruple charge transfer cross sections can be scaled using the second, third, and fourth ionization potentials, respectively.
