Opis

Examining new applications and developments, Core Level Spectroscopy of Solids examines fundamental and theoretical aspects of x-ray and electron spectroscopies, including x-ray absorption, x-ray photoemission, Auger electron spectroscopy, and resonant inelastic x-ray scattering. The book explains which models are appropriate for which systems and spectroscopies. The emphasis on interpreting these spectroscopies stems from models based on charge transfer multiplet theory. Presenting a large range of new applied spectroscopy developments and containing more than 150 illustrations, Core Level Spectroscopy of Solids makes an ideal reference for the research community.
