Record 2 2009-11-09

English

Subject field(s)
  • Nuclear Physics
CONT

Elastic scattering of neutrons by nuclei can occur in two ways. The more usual of the two interactions is the absorption of the neutron, forming a compound nucleus, followed by the re-emission of a neutron in such a way that the total kinetic energy is conserved and nucleus returns to its ground state. This is known as resonance elastic scattering(a collision where a nucleus absorbs a neutron and re-emits it, conserving kinetic energy).

Record 3 2009-10-26

English

Subject field(s)
  • Nuclear Physics
CONT

The neutron resonance absorption spectroscopy(N-RAS) is a method to study the dynamics of nuclides by analyzing the Doppler broadening of their resonance spectra.

French

Domaine(s)
  • Physique nucléaire
CONT

L'extrême complexité des courbes de sections efficaces des noyaux lourds, notamment l'uranium 238, dans le domaine du ralentissement des neutrons rend le problème du calcul de l'absorption résonnante des neutrons particulièrement ardu.

Record 4 2009-03-01

English

Subject field(s)
  • Atomic Physics
DEF

The integral over all or some specified portion of the resonance energy range of the quotient of the absorption cross section... of a nuclide by the neutron energy E.

OBS

This term should not be confused with the excess resonance integral.

French

Domaine(s)
  • Physique atomique
DEF

Intégrale sur tout ou partie du domaine des énergies de résonance du quotient de la section efficace d'absorption [...] d'un nucléide par l'énergie E des neutrons.

OBS
