begins with an overview of the physics underlying the collisions involved in discharge, scattering, ion mobilities, and the various cross-sections and relations between them. A discussion follows on experimental techniques used to measure collision cross-sections, covering the techniques related to the data presented in later chapters. In an unprecedented collection of data and analysis, the author supplies comprehensive cross-sections for rare gases such as Argon, Helium, Krypton, and Xenon; various diatomics; and complex molecules and industrial gases including hydrocarbons. He further includes discussions and analyses on drift and diffusion of electrons, ionization coefficients, attachment coefficients, high-voltage phenomena, and high-frequency discharges. Based on more than 40 years of experience in the field, places a comprehensive collection of data together with theory and modern practice in a single, concise reference.
