Heteronuclear Associative Ionization of Argon with Nitrogen and Carbon Monoxide
Pulsed mass-spectrometric studies of the bimolecular formation of ArN2+, ArCO+, and Ar2+ in argon-nitrogen mixtures and argon-carbon monoxide mixtures subjected to the impact of 30 eV electrons show that all three reactions proceed with essentially the same specific reaction rate of 1.5×10−9 cm3/sec...

| description | Pulsed mass-spectrometric studies of the bimolecular formation of ArN2+, ArCO+, and Ar2+ in argon-nitrogen mixtures and argon-carbon monoxide mixtures subjected to the impact of 30 eV electrons show that all three reactions proceed with essentially the same specific reaction rate of 1.5×10−9 cm3/sec. The effective lifetime of the argon atoms producing ArN2+ is longer than that of the argon atoms forming Ar2+, while the reverse is true in a comparison of the effective lifetimes for ArCO+ and Ar2+ formation. On the basis of the dependence of the ratio ArN2+/Ar2+ on electron energy and the time delay between electron pulse and ion-drawout pulse, it is concluded that ArN2+ has a threshold energy lower than Ar2+. The same is probably true of ArCO+ but the effect of delay time in this case is complicated by dissimilar shapes of the pertinent ionization-efficiency curves. It is suggested that Penning ionization of CO becomes progressively more important for the higher-lying states of argon. |
