Record 2 2015-04-24

English

Subject field(s)

OBS

Fermi age theory: term and definition standardized by ISO.

French

Domaine(s)
  • Physique atomique
DEF

Théorie du ralentissement des neutrons dans laquelle l'hypothèse essentielle est que le processus de ralentissement est continu et que le transport des neutrons dans l'espace peut être traité à l'aide de la théorie de la diffusion.
