Neutron yields from actinide oxides

Neutron yields emitted from actinide oxides by spontaneous fission and by the (α,n) reaction of oxygen were measured separately. The measured neutron yields of spontaneous fission were consistent with the neutron yields calculated from v-bar-values and rates of spontaneous fission. The (α,n) neutron yields calculated from stopping power and thick target yield data were lower than the measured yields by about 10%. (author)
