Abstract
Background: The design of new nuclear reactors and transmutation devices requires to reduce the present
neutron cross section uncertainties of minor actinides.
Purpose: Improvement of the 243Am(n,¿ ) cross section uncertainty.
Method: The 243Am(n,¿ ) cross section has been measured at the n_TOF facility at CERN with a BaF2 total
absorption calorimeter, in the energy range between 0.7 eV and 2.5 keV.
Results: The 243Am(n,¿ ) cross section has been successfully measured in the mentioned energy range. The
resolved resonance region has been extended from 250 eV up to 400 eV. In the unresolved resonance region
our results are compatible with one of the two incompatible capture data sets available below 2.5 keV. The data
available in EXFOR and in the literature have been used to perform a simple analysis above 2.5 keV.
Conclusions: The results of this measurement contribute to reduce the 243Am(n,¿ ) cross section uncertainty and
suggest that this cross section is underestimated up to 25% in the neutron energy range between 50 eV and a few
keV in the present evaluated data libraries.
