High-resolution cross section measurement for 236U(n, f)

Measurement of the 236U(n,f) cross section at fast neutron energies with Micromegas Detectors

“…The most recent measurement has been performed by Tovesson et al [3] with the neutron time-of-flight method at LANSCE (Los Alamos). The rest of the measurements have been performed several decades ago with quasimonoenergetic neutron beams by Meadows [4] and White and Warner [5] and in a wide energy range by Rosler et al [6] and Henkel [7]. The measurements by Tovesson et al, Meadows and Rosler et al are in overall good agreement with each other, although above 7 MeV the data from Rosler et al deviate from the other two measurements and the differences go up to 40%.…”

“…2. Had they, they would have found excellent agreement with all of the data save the Rosler, Plasil, Schmitt data [9] and the Henkel data [10]. Neither set was published, neither contain uncertanties, and neither provide documentation; therefore they may be safely excluded from consideration.…”

“…In a parallel attempt, Schmitt et al [13] used the 33 m flight path at the Oak Ridge Electron Linear Accelerator (ORELA) to study the structures in the cross section around the fission threshold. The energy resolution obtained in this experiment was 0.7% at 1 MeV.…”
