Post-neutron mass distribution for 238Pu(nth, f)

Abstract The yields of 51 fission products in 36 mass chains produced in 238 Pu(n th , f) have been determined via γ-ray spectroscopy. The mean number of neutrons per fission was found to be 〈ν T 〉 = 2.5 ± 0.2. A mean proton odd-even effect δ p = (14 ± 3)% was also deduced for 9 mass chains. These results are discussed in terms of the existing data on other fissioning nuclei.
