Data analysis and evaluation with SAMMY

This lecture is focusing on the common practice utilized to perform data evaluation, in particular, the evaluation procedure used for data analysis in the resolved-energy region using the reduced R-matrix formalism, i.e. the Reich-Moore approximation. When using the SAMMY program for data evaluation, a minimum of three files are required to initiate the evaluation, containing the experimental conditions including flight-path length, temperature, sample thickness, resolution parameters, resonance spin information; the initial estimation of the resonance parameters and a file containing the data to be evaluated. To illustrate how to perform an evaluation using SAMMY, an example using the total cross sections for 235U is presented
