electron — One of the negatively charged subatomic particles that orbit the positive nucleus, in one of several energy levels called shells; in mass they are estimated to be 1/1836.15 of a proton; when emitted from inside the nucleus of a radioactive… … Medical dictionary
CONVERSION — Selon sa signification étymologique, conversion (du latin, conversio ) signifie retournement, changement de direction. Le mot sert donc à désigner toute espèce de retournement ou de transposition. C’est ainsi qu’en logique le mot est employé pour … Encyclopédie Universelle
Conversion interne — La conversion interne est un mode de désintégration radioactive par lequel un électron acquérant directement l énergie d excitation d un noyau atomique s en trouve expulsé de l atome. Il y a donc émission d un électron énergétique, mais en dehors … Wikipédia en Français
Émission bêta — Radioactivité β La radioactivité bêta ou émission bêta (symbole β) est un type de désintégration radioactive dans laquelle une particule bêta (un électron ou un positron) est émise. On parle de désintégration bêta moins (β ) (basse énergie) ou… … Wikipédia en Français
Conversion intersystème — L UICPA décrit la conversion intersystème comme[1]: « Un processus photophysique. Une transition à énergie constante, sans émission de rayonnement, entre deux états électroniques de multiplicités différentes. Cela conduit généralement à l… … Wikipédia en Français
Internal conversion — This article is about the nuclear process. For the chemical process, see Internal conversion (chemistry). Internal conversion is a radioactive decay process where an excited nucleus interacts with an electron in one of the lower atomic orbitals,… … Wikipedia
