Abstract

Emission spectra resulting from reaction of "clean" N2(A3 Σu+) with copper atoms were studied using a flowing afterglow apparatus. The population distribution of the Cu states was calculated from the spectrum; it indicates that Cu atoms are excited by nearly resonant energy transfer processes. N2(A,v') + Cu(2S 1 2) → N2(X, v) + Cu*, and that the transfer is most efficient for N2(A,v') → N2(X,v) transitions with large Franck-Condon factors. The preferential energy transfer results in population inversion between some of the Cu states.
