… the NPET [non-pure positron emission tomography] system consists of two types of detection systems. The first type of detection system is referred to as a PET [positron emission tomography] subsystem and the second type of detection system is referred to as a SPECT [single photon emission computed tomography] subsystem. These two subsystems are connected by a triple coincidence circuit. The PET subsystem simultaneously detects two annihilated photons (511 KeV [kiloelectronvolts]). The direction of the annihilated photons (called annihilation line) is along the line of response (LOR) connected by the two detectors that coincidentally intercept the photons.  1, record 5, English, - annihilation%20line

Discovery of cataclysmic variables ... Verifying that an object is a cataclysmic variable is also fairly straightforward: they are usually quite blue objects, they exhibit rapid and strong variability, and they tend to emit in the ultraviolet and X-ray ranges; they are expected also to emit gamma rays, from annihilation of positrons from proton-rich nuclei produced in the fusion explosion ...  3, record 7, English, - positron%20annihilation

Usually an "atom" of positronium (e+e-) forms which annihilates to produce two 511-keV photons. Occasionally, the positron will annihilate in flight to produce one or more photons sharing the total rest mass and kinetic energy of the positron and electron.  3, record 7, English, - positron%20annihilation

Annihilation des positons. Cette méthode permet de mesurer le temps de vie des positons piégés par tout défaut provoquant une diminution de la densité électronique locale [...] Elle est donc non seulement sensible à la présence de lacunes et petites cavités, mais également à celle de certains précipités. Toutefois, l'interprétation des résultats obtenus par cette technique s'avère parfois délicate.  1, record 7, French, - annihilation%20des%20positons
