Photoionization - Wikipedia
WebPhotoionization is the process that makes once-invisible filaments in deep space glow. Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule.
Photoelectrochemical process - Wikipedia
WebPhotoionization is the physical process in which an incident photon ejects one or more electrons from an atom, ion or molecule. This is essentially the same process that occurs with the photoelectric effect with metals. In the case of a gas or single atoms, the term photoionization is more common.
Photo-ionization | Photoelectron, Electron Emission, Photon
WebPhoto-ionization, the interaction of electromagnetic radiation with matter resulting in the dissociation of that matter into electrically charged particles. The simplest example, the photoelectric effect (q.v.), occurs when light shines on a piece of metal, causing the ejection of electrons.
Photoionization of Atoms | SpringerLink
WebThis chapter outlines the theory of atomic photoionization, and the dynamics of the photon-atom collision process. Those kinds of electron correlation that are most important in photoionization are emphasized, although many qualitative features can be understood within a central field model. The particle-hole type of electron correlations are ...
