IONIZATION AND DISSOCIATIVE IONIZATION OF O(2) AFTER ELECTRON AND ION IMPACT

Abstract

The ionization of O2 was investigated by using charge exchange in a double mass spectrometer. The breakdown graph was constructed. A break in the electron impact ionization efficiency curve is explained as being due to ion- molecule reactions between excited O(+) ions formed in an ion-pair process, and O2. It is shown that the cross sections must be very small for the reaction O(+) (quadruplet-S) + O2 to O + O2(+) since the cross sections for the corresponding reaction with Si(+) are small. Implications for the aeronomy are discussed.
