  2. 6. Angular momentum generation in nuclear fission

    Invited Talk

    When a heavy atomic nucleus fissions, the resulting fragments are observed to emerge spinning; this phenomenon has been an outstanding mystery in nuclear physics for over 40 years. The internal generation of around 6-7 units of angular momentum in each fragment is particularly puzzling for systems which start with zero, or almost zero, spin. There are currently no experimental observations...

  3. 18. Excitation energy dependence of prompt fission $\gamma$-ray emission from $^{241}Pu^*$

    Prompt fission $\gamma$ rays (PFGs) resulting from the ${^{240}Pu}$($d$,$p$f) reaction have been measured as a function of fissioning nucleus excitation energy $E_\text{x}$ at the Oslo Cyclotron Laboratory. We study the average total PFG multiplicity per fission, the average total PFG energy released per fission, and the average PFG energy. No significant changes in these characteristics are...

    Independent yield distributions of high-energy neutron-induced fission is of importance to achieve a good understanding of the fission process. Further more, these data also plays an important role in the development of Generation IV nuclear reactors. While the mass and charge yield distributions of thermal neutron-induced fission is well known, there is a lack of experiment data for...

  5. 11. Determination of the Plasma Delay Time in PIPS detectors for fission fragments with the LOHENGRIN spectrometer

    The particle spectrometer VERDI (VElocity foR Direct particle Identification) allows high-precision measurements of fission fragment (FF) yield by using the so-called 2E-2v technique. The spectrometer allows the determination of the FF mass, both before and after neutron emission, by means of a time-of-flight (ToF) and energy measurement. VERDI consists of two arms with 16 Silicon PIPS...

    The neutron emission is an important signature of the energy sharing in the nuclear fission process. Highly excited, neutron-rich nuclei release their energy by emitting prompt neutrons and γ-rays. Improved determination of particle-emission characteristics enhances the understanding of fission dynamics. The nuclear data libraries lack data which are crucial for these areas, especially the...

  7. 17. Rapid detection and localization of special nuclear materials

    ABSTRACT
    We have developed a method for sensitive detection and localization of special nuclear materials (SNM) within the context of an organic scintillator based radiation portal monitor (RPM) prototype system. The method uses fast time and energy correlations between gamma-rays and neutrons from spontaneous fission, and may be used as an additional detection modality, besides single...
