This book presents a focused exploration of electron-atom and electron-molecule scattering, emphasizing both theoretical and practical aspects. It begins by establishing the significance of scattering processes in understanding atomic and molecular structures, as well as their interactions. Special attention is given to the distinct roles of electrons and positrons as projectiles, shedding light on how their differing characteristics influence scattering behavior. The work also highlights the relevance of metastable targets and their applications in modern research. The theoretical framework...

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 H2* and N2*. Chapter 2 focuses on the calculation of total ionization cross sections for NF molecules, silicon chloride radicals, and larger tetrahedral molecules like...
