SAMINT: A New Evaluation Tool to Perform Resonance Parameter Data Adjustments based on Integral Experiment Data

摘要

The objective of this work is to enable the coupling of differential and integral data evaluation in a continuous-energy framework and, more specifically, to use the Generalized Linear Least-Squares (GLLS) methodology employed in the TSURFER module of the SCALE code package to update the parameters of a resolved resonance region evaluation directly. Recognizing that the GLLS methodology in TSURFER is identical to the mathematical description of a simple Bayesian update carried out in SAMMY, the computer code SAMINT was created to help use the mathematical machinery of SAMMY to update resolved resonance parameters based on integral data. Minimal modifications of SAMMY are required when used with SAMINT to make resonance parameter updates based on integral experimental data.
