Abstract

A method based on Bayes principle has been developed. Using it the crosssections for a nuclide at the single same energy point can be adjusted to meet oneor two kinds of consistence relation simultaneously (e. g. σ_1=σ_(nn)+σ_(nn')+σ_(nγ)+σ_(nχ)+……, σ_(non)=σ_(nn'),+σ_(nγ)+σ_(nχ)+……)and the covariance matrix at the sameenergy point can be calculated. A program is available for this.
- Nuc1ear data joint adjustment,
- Systematic error processing
