fotóionizuje

Fotóionizuje is a term used in the field of physics, specifically in the context of atomic and molecular physics. It refers to the process by which an atom or molecule absorbs energy in the form of a photon and ejects one or more electrons from its outer shell. This process is known as photoionization.

The energy of the photon must be at least equal to the ionization energy of the atom or molecule for the process to occur. If the photon's energy is greater than the ionization energy, the excess energy may be carried away by the ejected electron or may cause further ionization.

Photoionization is an important process in various scientific and technological applications. In astrophysics, it is a key mechanism for the interaction of radiation with matter in stars and interstellar medium. In atmospheric science, it plays a role in the formation of the ionosphere. In laboratory settings, photoionization is used in mass spectrometry for the analysis of chemical compounds.

The term "fotóionizuje" is the Czech word for "photoionizes." The process is analogous to other ionization processes, such as electron impact ionization, where electrons collide with atoms or molecules to cause ionization. However, in photoionization, the energy source is electromagnetic radiation rather than a charged particle.
