Electron impact cross sections with O atoms; O2 and O3 molecules — a theoretical survey
Atomic oxygen together with O2 and O3 molecules forms a unique trio in the atomic-molecular regime. Besides the all-important O & O2 present in our atmosphere, ozone is a crucial factor in controlling UV radiations reaching Earth’s surface. Studies of electron impact on O2 are useful in the analysis of atmospheric phenomena like aurora and the airglow1. Investigations of electron scattering from these molecules have a variety of applications such as in gaseous electronics (e.g. discharge-dielectrics), plasma physics, and planetary atmospheres2. As against several cross section calculations and measurements available on O and O2 the electron scattering studies on the O3 molecules are only a few.
