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

Abstract

Single and multiple charge transfer cross sections for Ne^q+ (q = 2 - 6) ions were measured in collisions with Ne, Ar, Kr, and Xe atoms at 2q keV. Quintuple charge transfer cross sections σ_6,1 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.
