Definition

quotient of the number of internal conversion electrons and the number of gamma quanta emitted by the radioactive atom in a given transition, where a conversion electron represents an orbital electron emitted through the radioactive decay

quotient du nombre d'électrons de conversion interne par le nombre de photons gamma émis par l'atome radioactif au cours d'une transition donnée, un électron de conversion représentant un électron orbital émis par la désintégration radioactive

Notes

The quantity $α / (α + 1)$ is also used and called the internal-conversion fraction.

Partial conversion fractions referring to the various electron shells $K, L, \dots$ are indicated by $α_{K}, α_{L}, \dots$ .

$α_{K} / α_{L}$ is called the $K$ -to- $L$ internal conversion ratio.

La grandeur $α / (α + 1)$ est aussi employée et peut être appelée fraction de conversion interne.

Les facteurs de conversion partielle correspondant aux différentes couches électroniques $K, L, \dots$ sont indiqués par $α_{K}, α_{L}, \dots$ .

$α_{K} / α_{L}$ est appelé rapport de conversion interne de $K$ à $L$ .
