Mass Spectrometer Investigation of Ionization of N2O by Electron Impact

The N2O molecule has been studied with a nearly monoenergetic electron beam. A result of the positive ion data is a value for D(N2–O) ≤ 1.34±0.2 ev and a value of D(N–NO) ≤ 4.50+0.10 ev. Measurements were made of the kinetic energies of the ions formed. N+ and N2+ are found to have zero kinetic energy at threshold. The production of an O− ion is observed with an appearance potential in the range 0 to 0.05 ev.
