摘要：
The mechanism of the formation of the prompt-neutron spectrum in fissioning of U-235 and Pu-239 by thermal and fast neutrons and spontaneous fission of Cf-252 is investigated A method is proposed for the formation of the prompt-neutron spectrum in fissioning of nuclei as a superposition of three partial Weisskopf evaporation spectra with average neutron energy 0.4, 2.06, and 2.8 MeV.
