Neutron-induced fission cross section of Np237 in the keV to MeV range at the CERN n_TOF facility

Μ. Diakaki, D. Karadimos, R. Vlastou, Michael Kokkoris et autres

The neutron-induced fission cross section of $^{237}\mathrm{Np}$ was experimentally determined at the high-resolution and high-intensity facility n_TOF, at CERN, in the energy range 100 keV to 9 MeV, using the $^{235}\mathrm{U}(n,f)$ and $^{238}\mathrm{U}(n,f)$ cross section standards below and above 2 MeV, respectively. …

Towards the high-accuracy determination of the238U fission cross section at the threshold region at CERN – n_TOF

Μ. Diakaki, L. Audouin, E. Berthoumieux, M. Calviani et autres

The 238U fission cross section is an international standard beyond 2 MeV where the fission plateau starts. However, due to its importance in fission reactors, this cross-section should be very accurately known also in the threshold region below 2 MeV. The 238U …

High accuracy235U(n,f) data in the resonance energy region

Carlos Paradela, I. Durán, L. Tassan-Gôt, L. Audouin et autres

The 235U neutron-induced cross section is widely used as reference cross section for measuring other fission cross sections, but in the resonance region it is not considered as an IAEA standard because of the scarce experimental data covering the full region. In …

High-accuracy determination of the U238/U235 fission cross section ratio up to ≈1 GeV at n_TOF at CERN

Carlos Paradela, M. Calviani, Diego Tarrío, E. Leal-Cidoncha et autres

The $^{238}\mathrm{U}$ to $^{235}\mathrm{U}$ fission cross section ratio has been determined at n_TOF up to $\ensuremath{\approx}1$ GeV, with two different detection systems, in different geometrical configurations. A total of four datasets has been collected and compared. They are all consistent to each …
