Main Points of the Theory of Photoabsorption


As photoabsorption or photoionization in this book we consider a process, in which a photon of energy ω and momentum κ, κ ;= ω ∕ c (c is the speed of light) is absorbed by a target—an atom or an ion. As a result, the target object can be either excited or ionized. Excitation means a transition of an atom or ion to one or several discrete energy levels.
