摘要：
Measurements of the total delayed neutron yield from fast neutron induced fission of (238)U have been made using the experimental method based on the periodic irradiation of the fissionable sample by neutrons from a suitable nuclear reaction. The preliminary results on the energy dependence of the total delayed neutron yield are presented. According to the comparison of the experimental data with our prediction based on correlation properties of delayed neutron characteristics, it is concluded that the value of the total delayed neutron yield near the threshold of the (n,f) reaction is not a constant.
