Abstract
In thermal plasma, the ion--atom collisions proceed most probably through resonance processes. One of the important processes is the resonant transfer excitation followed by emission of X-rays (RTEX), which causes self-cooling for plasma. In addition, it is identical to the dielectronic recombination (DR) in electron-ion collisions. The present work deals with the calculation of DR cross-sections (sDRs) and DR rate coefficients (aDRs) as well as RTEX cross-sections (sRTEXs) for Mg-like ions [Ar6+ and Kr24+] with L-shell and K-shell excitation for Dn = 0 and D n \neq 0. Comparison between the present results and other calculations for the rates are presented. RTEX cross-sections are calculated for the collision of Ar6+ and Kr24+ ions with He and H2 targets. The calculations are carried out using the adapted angular momentum average scheme in the isolated resonance approximation.
