Fotoniionisaatiolla
Fotoniionisaatiolla, or photoionization in English, is a physical process where an atom or molecule absorbs one or more photons and loses one or more electrons. This results in the formation of a positively charged ion and one or more free electrons. The energy of the absorbed photons must be sufficient to overcome the binding energy of the electron, also known as the ionization potential.
This phenomenon is fundamental to many areas of physics and chemistry. In astrophysics, photoionization plays a
In laboratory settings, photoionization is utilized in various spectroscopic techniques, such as photoelectron spectroscopy, to probe
