Record 1 2015-04-24

English

Subject field(s)
  • Atomic Physics
  • Nuclear Fission Reactors
DEF

A cross-section averaged over energy, employing appropriate weighting factors, to take into account the effect of thermal motion of the target particles.

OBS

The product of the average cross-section so obtained and the flux density in the laboratory system then gives the correct reaction rate.

OBS

Doppler-averaged cross-section: term and definition standardized by ISO.

French

Domaine(s)
  • Physique atomique
  • Réacteurs nucléaires de fission
DEF

Section efficace moyenne calculée d'après l'énergie en utilisant des facteurs de pondération appropriés, de façon à tenir compte de l'effet du mouvement thermique des particules cibles.

OBS

Le produit de la section efficace ainsi obtenue par la densité de flux dans le système du laboratoire donne le taux de réaction exact.

OBS

section efficace moyenne Doppler : terme et définition normalisés par l'ISO.
