241Am(n,f) and 243Am(n,f)
The nuclei ^{241}Am and ^{243}Am are important in the nuclear wastes and could be completely removed from the used fuel and then burnt through the incineration with fast neutrons.
- The first experiment involved the measurement of the cross-section for reaction ^{243}Am(n,f) induced by fast-neutrons.
The experiment was realized in Belgium, at IRMM of Geel at van de Graaff accelerator with neutrons from 1 to 8 MeV obtained via the reaction ^{3}H(p,n). The experimental set-up is shown below: the fission fragments were detected with solar cells, the neutron flux was monitored via the reaction (n,p) on the hydrogen film.
Preliminary results are reported on the following figure:
- New experiments on ^{243}Am are scheduled at CENBG AIFIRA accelerator to measure the mass distribution of fission products with fast neutrons (energy>1 MeV).
Lastly the measurement of the cross-section for 241Am(n,f) reaction depends on the availability of the target that is very radioactive and delicate in usage.
