NOYAU RECUL [1 record]

Record 1 2009-11-18

English

Subject field(s)
  • Nuclear Physics
CONT

... another component of alpha radiation is the recoil of the parent nucleus, due to the conservation of momentum requiring the parent nucleus to recoil, much like the 'kick' of a rifle butt when a bullet goes in the opposite direction. This gives a significant amount of energy to the recoil nucleus, which also causes ionization damage.

French

Domaine(s)
  • Physique nucléaire
DEF

Noyau qui, par suite d'une réaction nucléaire ou d'une émission radioactive, est doué d'une énergie cinétique due à cette réaction ou à cette émission.

OBS

Dans le cas d'une désintégration alpha, par exemple, l'énergie libérée se retrouve sous forme d'énergie cinétique partagée entre la particule alpha (98 %) et le noyau qui recule (2 %).
