摘要：

The cross sections for neutron-induced fission of Np-237, Am-242m, and Cm-245 have been measured in the energy range from 0.1 eV to 2 keV using the lead slowing-down neutron spectrometer at the Research Reactor Institute, Kyoto University. The fission cross sections were deduced relative to those for U-235(n,f) and B-10(n,a). The cross section for Np-237(n,f) was obtained with the experimental uncertainty of about 20% in the energy region below 25 eV and typically 13% above this energy. The experimental uncertainties for Am-242m and Cm-245 were, respectively, of the order of 14% and 9% in the entire energy region.
