The line is of great interest in Big Bang cosmology because it is the only known way to probe the cosmological "dark ages" from recombination (when...

In cosmology, recombination refers to the epoch during which charged electrons and protons first became bound to form electrically neutral hydrogen atoms...

quantum-mechanical optical recombination rate. Doping is additionally used to determine the wavelength of photon emission. An OLED display works without...

lost (normally through the emission of a photon of that energy, but there are a variety of possible processes). Recombination places an upper limit on the...

stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of...

The analysis of line intensity ratios is an important tool to obtain information about laboratory and space plasmas. In emission spectroscopy, the intensity...

The first detection of such a radio recombination line (RRL) was by Soviet radio astronomers in 1964; the line, designated H90α, was emitted by hydrogen...

violated. For radiative recombination to occur in an indirect band gap material, the process must also involve the absorption or emission of a phonon, where...

source of stimulated spectral line emission, typically in the microwave portion of the electromagnetic spectrum. This emission may arise in molecular clouds...

A nearby photon with energy equal to the recombination energy can cause recombination by stimulated emission. This generates another photon of the same...

features of Fast Low-Ionization Emission Region (FLIER). The central star of M2-42 is classified as weak emission-line star, but its nitrogen and helium...

incoming light. In semiconductor optical amplifiers (SOAs), electron–hole recombination occurs. In Raman amplifiers, Raman scattering of incoming light with...

Sound amplification by stimulated emission of radiation (SASER) refers to a device that emits acoustic radiation. It focuses sound waves in a way that...

phase transitions of gas in the universe[citation needed] (the first is recombination). While the majority of baryonic matter in the universe is in the form...

Airglow (also called nightglow) is a faint emission of light by a planetary atmosphere. In the case of Earth's atmosphere, this optical phenomenon causes...

reported on infrared emission from gallium arsenide (GaAs) and other semiconductor alloys in 1955. Braunstein observed infrared emission generated by simple...

biological phenomenon of triboluminescence is thought to be controlled by recombination of free radicals during mechanical activation. Certain household materials...

in dense gas, •HO is mainly formed by dissociative recombination of H3O+. Dissociative recombination is the reaction in which a molecular ion recombines...

open channel unusable and the ionization disappears quickly because of recombination at low altitude and high atmospheric pressure. Although the hot lightning...

describe luminescence of semiconductors resulting from spontaneous recombination of electronic excitations, producing a flux of spontaneously emitted...
