摘要：

The Am-242m and Cm-245 fission cross sections in the neutron energy range 0.03 eV-20 keV were measured with a SVZ-1000 lead slowing-down neutron spectrometer at the Institute for Nuclear Research of the Russian Academy of Sciences. The procedure for analyzing the experimental data relies on the SVZ mathematical model (based on the Monte Carlo method), which makes it possible to expand the dynamical range of the spectrometer into the thermal-neutron range. The parameters of the model were chosen on the basis of the best description of the measured fission cross sections for the nuclear standards U-235 and Pu-239.
