Definition

differential quotient of $σ$ with respect to energy, where $σ$ is the cross section (cross section <atomic physics>) for a process in which the energy $E$ (ISO 80000-5: Thermodynamics) of the ejected or scattered particle is between $E$ and $E + d E$ :

σ_{E} = d σ / d E

quotient différentiel de $σ$ par rapport à l'énergie, où $σ$ est la section efficace (cross section <atomic physics>) pour un processus dans lequel l'énergie $E$ (ISO 80000-5: Thermodynamics) de la particule émise ou diffusée est comprise entre $E$ et $E + d E$ :

σ_{E} = d σ / d E
