Sekundärjonisation

Sekundärjonisation, also known as secondary ionization, is a process in which an atom or molecule is ionized by the interaction with an already existing ion. This phenomenon is significant in various fields, including plasma physics, astrophysics, and atmospheric science. In plasma physics, secondary ionization occurs when a neutral atom collides with an ion, resulting in the atom being ionized and the ion losing energy. This process can lead to a cascade of ionizations, contributing to the overall ionization rate in a plasma. In astrophysics, secondary ionization plays a crucial role in the ionization of interstellar gas, influencing the chemical composition and physical properties of these regions. In atmospheric science, secondary ionization is involved in the formation of ions in the Earth's atmosphere, which can affect cloud formation and other atmospheric processes. The study of sekundärjonisation provides valuable insights into the behavior of ions and their interactions in various environments.
