In this document, we present the nal result obtained at the n TOF experiment for the neutron- induced ssion cross section of the 237Np, from the ssion threshold up to 1 GeV. The method applied to get this result is brie y 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.
