Description

Bayes approach for combined analysis of partial neutron cross sections and neutron transmission functions for rather thick samples is applied. Two methods: interference analysis on the base of Adler-Adler formalism in the range of resolved resonances as well as simulation of neutron cross sections and their functionals using Reich-Murr approximation for non-resolved resonances are considered. Dispersions of estimated parameters with and without account of data obtained from the transmission function and self-indication are copared as an intermediate result. Their posterior distribution is used for estimation of parameters, expiicit form of the correction to the aprioric value is obtained at variation of parameters. Specified value of resonance parameters at the expense of including data on neutron transmission through thick specimens into analysis of the resonance structure is estimated
