0 the process of forming an ion or causing something to form an ion:
Widespread ionization occurs readily in Earth's upper atmosphere.
We use the term dissociation to describe the ionization of acids in water.
1 the process by which an ion is produced
It is based on the amount of ionization produced in a standard volume of air by X-rays.
Critics say these ionization alarms are also too quick to sense cooking smoke.
Ionization may be caused by firing light or electrons on to atoms, or by passing an electric spark through gas.
An interesting lack of uniqueness occurs in the case of flows past purely magnetic obstacles if the ionization is produced in a bow shock.
Supersonic ionization wave driven by radiation transport in a short-pulse laser-produced plasma.
The presence of the diamagnetic current requires a certain degree of ionization.
Furthermore, the recombination in the presence of a neutral body (wall) is important at a low degree of ionization.
