Towards the high-accuracy determination of the 238 U fission cross section at the thres hold region at CERN – n_TOF. EPJ Web of Conferences, 111 (02002), 02002-1-02002-6.2100-014Xhttp://hdl.handle.net/11441/49557The 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 fission cross section has been measured relative to the 235U fission cross section at CERN – n_TOF with different detection systems. These datasets have been collected and suitably combined to increase the counting statistics in the threshold region from about 300 keV up to 3 MeV. The results are compared with other experimental data, evaluated libraries, and the IAEA standardsapplication/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1051/epjconf/201611102002https://idus.us.es/xmlui/handle/11441/49557
