Electron-induced dynamics of small molecules of atmospheric and astrochemical relevance

Thesis

Electron ionisation, and electron scattering in general, is a fundamental physical process. Ubiquitous in the known universe, the interaction of electrons with molecules is thus of great interest.

From experimental and theoretical studies, we can obtain great insight into electron ionisation. We have used the binary-encounter-Bethe model to determine theoretical total ionisation cross-sections, which quantify the ionisation probability for a molecule. We also use an electron-molec...
