Double ionization is a process of formation of doubly charged ions when laser radiation or charged particles like electrons [1], positrons [2] or heavy ions [3] are exerted on neutral atoms or molecules. Double ionization is usually less probable than single-electron ionization. Two types of double ionization are distinguished: sequential and ...
It is a cascade reaction involving electrons in a region with a sufficiently high electric field in a gaseous medium that can be ionized, such as air. Following an original ionization event, due to such as ionizing radiation, the positive ion drifts towards the cathode , while the free electron drifts towards the anode of the device.
[10] [5] ALMA observations detected an emission line associated with doubly ionized oxygen (O III) at 258.7 GHz with a significance of 5σ, suggesting that there is very low dust content in GLASS-z12, if not the early universe as well. [2] Also based on oxygen-related measurements, the age of the galaxy is confirmed. [11] [12]

Emission nebulae mainly radiate the doubly ionized oxygen in the visible spectrum, which emits near 500 nm wavelength. These nebulae also radiate weakly at 486 nm, the Hydrogen-beta line. There are two main types of Narrowband filters: Ultra-high contrast (UHC), and specific emission line(s) filters.
