Neutron-Induced Fission Cross Sections of 240Pu, 243Am, and natW in the Energy Range 1–200 MeV

The neutron‐induced fission cross‐section ratios relative to 235U has been measured for 240Pu, 243Am and natW in a wide energy range of incident neutrons from 1 MeV to 200 MeV at the GNEIS facility. The measurements were performed using the multiplate ionization chambers and time‐of‐flight techniques. The results obtained in this measurement are presented in comparison with the other data.
