title: Determination of relative krypton fission product yields from 14 MeV neutron induced fission of238U at the National Ignition Facility.
abstract: Precisely-known fission yield distributions are needed to determine a fissioning isotope and the incident neutron energy in nuclear security applications. 14 MeV neutrons from DT fusion at the National Ignition Facility induce fission in depleted uranium contained in the target assembly hohlraum. The fission yields of Kr isotopes (85m, 87, 88, and 89) are measured relative to the cumulative yield of88Kr and compared to previously tabulated values. The results from this experiment and England and Rider are in agreement, except for the85mKr/88Kr ratio, which may be the result of incorrect nuclear data.
