Abstract : The report describes investigations of collision induced luminescence phenomena in high pressure argon and krypton containing trace amounts of N2 and O2 using nominal 2.5 Mev electrons as the primary energy source. High resolution spectroscopy demonstrates that the C triplet-pi state of N2 is produced by quenching of the set of argon levels corresponding to approximately 11.5 ev of excitation energy. Evidence is also presented for the occurrence of the reaction N2 (B triplet-pi-g + O2 (X triplet-Sigma-g-) to NO (A double-Sigma +) + NO (X doublet-pi). (Author)
