Neutron-induced fission cross section of Np-237 in the keV to MeV range at the CERN n_TOF facility

The neutron-induced fission cross section of 237Np 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 235U(n,f ) and 238U(n,f ) cross section standards below and above 2 MeV, respectively. A fast ionization...
