... an atom in an excited state E2 will eventually decay of its own accord to a state of lower energy E1, emitting a photon of energy E2 - E1 as it does so. This process is called spontaneous emission.... 2, record 1, English, - spontaneous%20emission

Émission spontanée : l'atome descend spontanément [...] à un niveau inférieur [...] en émettant un grain de lumière, ou photon, qui emporte l'énergie excédentaire. 3, record 1, French, - %C3%A9mission%20spontan%C3%A9e

L'émission spontanée est un phénomène aléatoire produisant des photons qui ne sont pas cohérents entre eux. 4, record 1, French, - %C3%A9mission%20spontan%C3%A9e

«fluorescence» : Ce stockage [d'énergie] [...] se termine par la réémission, dans une direction quelconque, d'un photon de même énergie que le premier. C'est ce que l'on appelle l'émission «spontanée» (ou fluorescence). 2, record 1, French, - %C3%A9mission%20spontan%C3%A9e
Record number: 1, Textual support number: 1 OBS
«fluorescence» : Orszag semble un des seuls auteurs à employer «fluorescence» comme synonyme d'émission spontanée. «Fluorescence» est moins courant dans ce sens et risquerait de créer une ambiguïté avec le sens le plus courant utilisé en physique. 5, record 1, French, - %C3%A9mission%20spontan%C3%A9e
