Background: The design of new nuclear reactors and transmutation devices requires to reduce the present neutron cross section uncertainties of minor actinides.Purpose: Reduce the 243 Am(n,γ) cross section uncertainty. Method:The 243 Am(n,γ) cross section has been measured at the n TOF facility at CERN with a BaF 2 Total Absorption Calorimeter, in the energy range between 0.7 eV and 2.5 keV.Results: The 243 Am(n,γ) 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 has been used to perform a simple analysis above 2.5 keV. Conclusions:The results of this measurement contribute to reduce the 243 Am(n,γ) 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. PACS numbers: 25.40.Lw,28.20.Np,27.90.+b 4
