In the context of the n{sub T}OF Collaboration, the measurement of the cross section of the reaction {sup 241}Am(n,2n){sup 240}Am, has been performed, for the first time at neutron energies from 8.8 to 11.4 MeV, by the activation method, relative to the {sup 27}Al(n,a){sup 24}Na reaction reference cross section. The monoenergetic neutron beam was produced at the 5.5 MV TANDEM accelerator of NCSR ''Demokritos,'' by means of the {sup 2}H(d,n){sup 3}He reaction, using a deuterium filled gas cell. The radioactive target consisted of a 37 GBq {sup 241}Am source enclosed in a Pb container. After the end of the irradiation, the activity induced by the neutron beam at the target and reference, was measured off-line by a 56% relative efficiency, HPGe detector.
