Covariance matrix of evaluated data for {sup 54,56}Fe calculated from nuclear reaction models
- Kyushu Univ., Fukuoka (Japan)
Covariance matrix of neutron induced {sup 54,56}Fe, reaction cross sections is generated from uncertainties of the experimental data and the nuclear reaction model parameters. An optical model is used to evaluate experimental total, differential elastic scattering cross sections. The covariance matrices of these cross sections are calculated from the uncertainties of neutron optical potential parameters. Cross sections of {sup 54,56}Fe(n, p), (n, {alpha}), (n, 2n), (n, Xp) and (n, X{alpha}) reactions are calculated with a Hauser-Feshbach and a precompound models, and their covariance matrices are calculated front the uncertainties of the optical potential parameters for neutron, proton, and a-particle, level density parameters, and a precompound parameter.
