Two mass- spectrometric devices, with two independent ion sources, are used to perform excitation measurement for O+ -N2 collision system. Quadruple filter technique has been used to measure a production of reactant O+ ion by precisely controlled electron impact ionization and fragmentation cross section of oxygen molecules. Optical spectroscopy device, incorporated with a RF ion source, is used to reveal an exact range of working pressure, in ion source, with respect to control a contamination of primary beam. The fractional percentage of oxygen ions in RF source, being in the ground 4S and in in the metastable 2D, 2P states, is estimated. The excitation cross section of molecule N2+ ion for (0,0); (0,1) and (1,2) band system in collision of O+ ion with nitrogen N2 molecules have been measured.
