Absolute measurements of emission cross sections have been performed for the lines from Arll excited states in Ar2++Li and Ar2++Na collision. The energy of incedent ions ranged from 40 keV to 300 keV. The dependence of the emission cross sections on the energy defect △E is discussed. We find that the processes with intermediate △E(>0) have larger cross sections. We also find that the excited states correlated to the observed lines belong to the high J quantum numbers in an electron configuration.
