Notes

For particles of energy $E$ (excluding rest energy), the radiant energy, $R$ , is equal to the product $N \cdot E$ where $N$ is the number of the particles that are emitted, transferred, or received

The distributions, $N_{E}$ and $R_{E}$ , of the particle number and the radiant energy with respect to energy are given by $N_{E} = d N / d E$ and +

$R_{E} = d R / d E$ , respectively, where $d N$ is the number of particles with energy between $E$ and $E + d E$ , and $d R$ is their radiant energy. The two distributions are related by $R_{E} = E \cdot N_{E}$ .

Pour des particules d'énergie $E$ (à l'exclusion de l'énergie au repos), l'énergie rayonnante, $R$ , est égale au produit $N \cdot E$ où $N$ est le nombre de particules émises, transférées ou reçues.

Les distributions, $N_{E}$ et $R_{E}$ , du nombre de particules et de l'énergie rayonnante par rapport à l'énergie sont données par $N_{E} = d N / d E$ et $R_{E} = d R / d E$ , respectivement, où $d N$ est le nombre de particules d'énergie comprise entre $E$ et $E + d E$ , et $d R$ est leur énergie rayonnante. Les deux distributions sont reliées par $R_{E} = E \cdot N_{E}$ .
