Radiative charge transfer in collisions of Ne²⁺ and of Ar²⁺ with H

Descriptions of charge exchange in collisions between ions and atoms are of fundamental importance and are widely applied. At low energies, for systems where direct charge exchange is negligible, a radiative charge exchange mechanism might be significant. For applications to ionized regions of astrophysical interest, we calculate the cross sections and rate coefficients corresponding to radiative charge transfer of Ne²⁺ and of Ar²⁺ with H at thermal energies.
