Abstract

Average cross sections for the unmoderated spontaneous fission neutron spectrum of 252Cf have been measured for 10 different threshold reactions by activation method. On the basis of the measured data and of the excitation functions the Maxwellian temperature for 252Cf neutron spectrum has been deduced and a value of T = 1.41 ± 0.02 MeV was found between 2.5 and 15 MeV. The temperature has been determined also from the average energy which was deduced from the age of epithermal neutrons in water measured by gold foil. The high 〈σ〉 values obtained by the low threshold reactions and the age method confirm the assumption on the excess of neutrons in the low energy region of the spectrum.
