Electron scattering studies with ground state & exotic targets

This book presents electron impact collision theories and results on exotic atoms and molecules. It introduces a simple method developed to estimate total elastic and inelastic (including ionization) cross sections for electron scattering from atoms and molecules. Chapter 1 examines electron impact with exotic targets such as atomic hydrogen and oxygen in both ground and excited states, as well as metastable molecules like H¿* and N¿*. Chapter 2 focuses on the calculation of total ionization cross sections for NF¿ molecules, silicon chloride radicals, and larger tetrahedral molecules like SiCl¿. The dissociation of SiCl¿ yields key components such as SiCl¿ (x = 1-3), relevant in plasma processes. Our group has also initiated theoretical work on the scattering of low-energy electrons by molecular targets. Chapter 2 briefly discusses low-energy calculations using the R-matrix method as implemented in the Quantemol-N software, which also provides Binary-Encounter-Bethe (BEB) ionization cross sections.
