Description

Knowledge on ($\alpha$,Xn) reactions is required in several fields:

• Nuclear structure. Most of our actual experimental knowledge on
  (α,Xn) reactions comes from nuclear structure experiments between the
  50’s and the 70’s. Nuclear technologies, non-proliferation and
  homeland security. $\alpha$-emitters present in fresh/irradiated
  nuclear fuels can create a neutron source through ($\alpha$-,Xn)
  reactions with (light) surrounding nuclei: fluorine, oxide and
  carbide fuels, vitrified nuclear waste…
• Determination of the ${}^{235}$U enrichment.
• Analysis of irradiated fuels, MOX fuels and fuels enriched in MA.
• Neutron background in underground experiments (nuclear astrophysics,
  Dark Matter) due to radiogenic $\alpha$-decay chains.

We will present some examples of applications and the SaG4n tool, a GEANT4-based parser that allows to perform realistic simulations of ($\alpha$,n) yields.
