Definition

sum of all cross sections (cross section <atomic physics>) corresponding to the various reactions or processes between an incident particle of specified type and energy (ISO 80000-5: Thermodynamics) and a target entity

somme de toutes les sections efficaces (cross section <atomic physics>) correspondant aux différentes réactions ou processus entre une particule incidente de type et d'énergie (ISO 80000-5: Thermodynamics) spécifiés et une entité cible

Notes

In the case of a narrow unidirectional beam of incident particles, this is the effective cross section for the removal of an incident particle from the beam. See the Remarks for atomic attenuation coefficient.

Dans le cas d'un faisceau parallèle mince de particules incidentes, il s'agit de la section efficace correspondant à l'élimination d'une particule incidente du faisceau. Voir les Remarques en atomic attenuation coefficient.
