Abstract : The purpose of this study was the measurement of electron impact ionization cross sections of metastable-molecules of N2. Cumulative cross sections calculated by classical techniques are more than an order of magnitude smaller than those determined from the electron impact measurements. Delayed emissions from the First and Second Positive Systems of N2 were measured. Experimental design and apparatus are described. Emissions are assigned and discussed.
