Physics-based method for generating probability table using random-matrix approach
K. Fujio, T. Kawano, A. E. Lovell +2
We develop a new method for generating probability tables based on a solid theoretical foundation. The fluctuating cross sections are calculated using the GOE--matrix model, in…
The Los Alamos evaluation of Pu neutron-induced reactions in the fast energy range
M. R. Mumpower, D. Neudecker, T. Kawano +5
A major revision of the evaluation of Pu neutron-induced reaction cross sections is reported in the fast energy range. The evaluation starts at 2.5 keV incident neutron ene…
Nuclear data activities for medium mass and heavy nuclei at Los Alamos
M. R. Mumpower, T. M Sprouse, T. Kawano +7
Nuclear data is critical for many modern applications from stockpile stewardship to cutting edge scientific research. Central to these pursuits is a robust pipeline for nuclear mod…
Collective enhancement in the exciton model
M. R. Mumpower, D. Nuedecker, H. Sasaki +5
The pre-equilibrium reaction mechanism is considered in the context of the exciton model. A modification to the one-particle one-hole state density is studied which can be interpre…
Energy Dependence of Prompt Fission Neutron Multiplicity in the Pu() Reaction
P. Marini, J. Taieb, D. Neudecker +11
Accurate multiplicities of prompt fission neutrons emitted in neutron-induced fission on a large energy range are essential for fundamental and applied nuclear physics. Measuring t…
Measurement of material isotopics and atom number ratio with alpha-particle spectroscopy for the NIFFTE fission Time Projection Chamber actinide target
M. Monterial, K. T. Schmitt, C. Prokop +37
We present the results of a measurement of isotopic concentrations and atomic number ratio of a double-sided actinide target with alpha-spectroscopy and mass spectrometry. The doub…
Measurement of the Pu(n,f)/U(n,f) Cross-Section Ratio with the NIFFTE fission Time Projection Chamber
L. Snyder, M. Anastasiou, N. S. Bowden +37
The Pu(n,f)/U(n,f) cross-section ratio has been measured with the fission Time Projection Chamber (fissionTPC) from 100 keV to 100 MeV. The fissionTPC provides thre…
Unrecognized Sources of Uncertainties (USU) in Experimental Nuclear Data
R. Capote, S. Badikov, A. Carlson +8
Evaluated nuclear data uncertainties are often perceived as unrealistic, most often because they are thought to be too small. The impact of this issue in applied nuclear science ha…
How accurately we know the standard Cf(sf) neutron multiplicity?
R. Capote, D. Neudecker
Small uncertainties obtained for the Neutron Standards have been associated with possible missing correlations in the input data, with an incomplete uncertainty budget of the emplo…
