Revisiting fission-probability data using $\mathcal{R}$-matrix Monte-Carlo simulations : application to Pu fissile isotopes over the 4 to 8 MeV excitation energy range

28 Feb 2019 Bouland O. Jurado B.

This article describes an original approach to analyze simultaneously cross sections and surrogate data measurements using efficient Monte Carlo extended $\mathcal{R}$-matrix theory algorithm based on unique set of nuclear structure parameters. The alternative analytical path based on the manifold Hauser-Feshbach equation was intensively used in this work to gauge the errors carried by the surrogate-reaction method commonly taken to predict neutron-induced cross sections from observed partial decay probabilities...
