Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule. [2] Not every interaction between a photon and an atom, or molecule, will result in …

Photo-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.), …

Photoionization is defined as the process in which a molecule expels an electron upon absorbing energy from one or more photons, resulting in the formation of radical cations.

Abstract This 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 …

In summary, photoionization involves the ionization of atoms or molecules by the absorption of photons with energies equal to or greater than the ionization potential.

The meaning of PHOTOIONIZATION is ionization (as in the ionosphere) of a molecule or atom caused by absorption of radiant energy.

Photoionization is a process in which a photon ejects one or more electrons from a neutral atmospheric particle (atom or molecule) turning it into a charged particle - an ion.

May 29, 2024 · Photoionization is a fundamental physical process wherein an atom or molecule absorbs a photon of light, causing an electron to gain enough energy to escape from the atom or molecule.

In this phenomenon, a photon of angular frequency is absorbed by an electron that occupies the ground state of a hydrogen atom. The final energy of the electron, where is the (negative) hydrogen ground …

Photoionization is a process of ionization by photons. It is one of the most important processes for studying astronomical objects.
