Neutron-induced fission cross section of Np up to 500 MeV

The simultaneous measurements of the angular distributions of fragments and the fission cross section of Np by neutrons in the energy range from 0.3 MeV to 500 MeV were carried out on the neutron time-of-flight spectrometer GNEIS at the Petersburg Nuclear Physics Institute of NRC "Kurchatov Institute". We presented a brief description of the experimental setup and compares the data obtained with the results of experiments performed earlier.
