Nuclear Science and Techniques

Measured relative ratios of the measured energy spectra correlated with different energy neutrons at 90° (a) and 180° (b) to the 252Cf prompt fission neutron energy spectrum.

Caption

The measurement results indicate that the influence of a neutron on the energy of the correlated neutron is more pronounced in the high energy region, and the related effect at 180° appears to be more noticeable than that at 90°. In addition to the difference in effect magnitude, the energy of the correlated neutron exhibits opposite trends between the correlated events at 90° and those at 180°. With the measured relative ratios, the related neutron energy spectra can be derived by multiplying the relative ratios by the 252Cf prompt fission spectrum recommended by IAEA.
