Analysis of old and recent experiments on thermoluminescence of cryocrystals and nanoclusters of N 2 , Ne, Ar, and Kr containing stabilized nitrogen atoms, suggests that the so-called γ-line may correspond to the bound-bound transition 1 D- 3 P of nitrogen anions N − formed in solids by the association of delocalized electrons and metastable nitrogen atoms N( 2 D). The recent observations of the γ-line were accompanied by simultaneous luminescence of metastable nitrogen N( 2 D) atoms and exoelectron emission. The fine structure of the γ-line at 793 nm has been experimentally observed and investigated for the first time.
