Abstract

In this document, we present the final result obtained at the n_TOF experiment; for the neutron-induced fission cross section of the Np-237, from the fission threshold up to 1 GeV. The method applied to get tins result is briefly discussed. n_TOF data are compared to the last experimental measurements using other TOF facilities or the surrogate method, reported experiments performed with monoenergetic sources and the FISCAL systematic, including a discussion about the existing discrepancies.
