Measurement of the cross section for the neutron-induced fission of $^{238}\mathrm{U}$ nuclei in the energy range of $0.3$–$500$ MeV

The cross section for the neutron-induced fission of $^{238}\mathrm{U}$ nuclei has been measured using the time-of-flight spectrometer of the GNEIS neutron complex at the Petersburg Nuclear Physics Institute, National Research Center Kurchatov Institute, in the neutron energy range of $0.3$–$500$ MeV. Fission fragments have been detected by low-pressure position-sensitive multiwire proportional counters. The cross section for $^{238}\mathrm{U}(n, f)$ fission has been measured with respect to the cross section for $^{235}\mathrm{U}(n, f)$ fission, which is an accepted international standard. Data on the energy dependence of the anisotropy of the angular distribution of fragments of neutron-induced $^{238}\mathrm{U}$ nuclei are also presented. The data obtained have been compared to previous experiments carried out using both similar and significantly different methods.
