22. First simultaneous evaluation of fission probabilities and neutron-induced cross sections for the Pu fissile isotopes

Surrogate reactions allow one to access to neutron-induced cross sections of short-lived nuclei, but require a consistent framework to relate measured deexcitation probabilities to neutron-induced observables. We present here the first application of the Monte Carlo R-matrix–extended formalism of O. Bouland (2019) to fissile 237-244Pu* isotopes. Neutron-induced cross sections and surrogate...

5. Random matrix approach for generating cross sections and probability table in the unresolved resonance region

Fluctuations in neutron-induced reaction cross sections in the unresolved resonance region (URR) influence the self-shielding effect. The self-shielding effect is generally evaluated by using the probability table method. The probability table provides the probability that the total cross section lies within a specified range, together with the corresponding average reaction cross sections. In...
