Excerpt
Introduction: Recently the present authors published compilations of cross-section data for the collision of electrons and photons with nitrogen (N,) and oxygen (0,)2 molecules. These molecules are the major constituents of the Earth's atmosphere. Atomic oxygen (0) is also important in the upper atmosphere of the Earth, since it is the most abundant species at heights between 200 and 600 km. Furthermore, atomic oxygen plays a significant role in the atmospheres of other planets (e.g., Venus and Mars) and in various astronomic objects. As an extension of the previous work on N, and O, the present paper compiles the cross-section data for the collision of electrons and photons with...
