摘要：

In the context of the n_TOF Collaboration, the measurement of the cross section of the reaction Am-241(n,2n)Am-240, has been performed, for the first time at neutron energies from 8.8 to 11.4 MeV, by the activation method, relative to the Al-27(n,a)Na-24 reaction reference cross section. The monoenergetic neutron beam was produced at the 5.5 MV TANDEM accelerator of NCSR "Demokritos," by means of the H-2(d,n)He-3 reaction, using a deuterium filled gas cell. The radioactive target consisted of a 37 GBq Am-241 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.
