Measurement of the neutron-induced fission cross-section of 241Am at the time-of-flight facility n TOF
The neutron-induced fission cross-section of 241Am has been measured relative to the standard fission cross-section of 235U between 0.5 and 20 MeV. The experiment was performed at the CERN n TOF facility. Fission fragments were detected by a fast ionization chamber by discriminating against the...

| 总结: | The neutron-induced fission cross-section of 241Am has been measured relative to the standard
fission cross-section of 235U between 0.5 and 20 MeV. The experiment was performed at the CERN n TOF
facility. Fission fragments were detected by a fast ionization chamber by discriminating against the α-
particles from the high radioactivity of the samples. The high instantaneous neutron flux and the low
background of the n TOF facility enabled us to obtain uncertainties of ≈ 5%. With the present results it
was possible to resolve discrepancies between previous data sets and to confirm current evaluations, thus
providing important information for design studies of future reactors with improved fuel burn-up. |
