Basic theory of electron scattering with atoms and molecules

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 adopted throughout offers a flexible and unified quantum mechanical approach for calculating various cross sections, enabling comprehensive analysis across a range of atomic systems. The results provide valuable insights into the scattering behavior of elements such as nitrogen, phosphorus, and arsenic, contributing to the broader field of atomic collision physics.
