Notizen: Abstract We present spectroscopic measurements of rate coefficients for the population of the ArI 6d[3/2] o and 8s[3/2] o states by two electron transfer from sputtered Cu to Ar2+ in an ECR microwave discharge. Rate coefficients are obtained from absolutely measured line intensities using a modified corona model. Though the binding energies of these states differ by 8 meV only the probability of populating the 6d level exceeds by a factor of ten that of populating the 8s level. This is attributed to an energy resonance between the two electrons when promoting to their final levels. The cross section for this two electron transfer comes out to be of the order of 10−15 to 10−14 cm2.
