| Abstract: | The vibrational population distribution of X 1Σ(υ′' = 0 through ν′' = 7) BaO formed in the reaction Ba + O2 at 0.3 torr has been measured by laser induced photoluminescence intensities. On the basis of the assumed similarity between the Ba + O2 and Ba + N2O reactions, these data suggest that a population inversion may exist between A 1Σ(ν′ = 1) and X 1Σ(υn = 7) BaO formed in the latter reaction at ≈ 16 torr. |
