Comparison of different average parameters for 232Th in the URR

In this report we compare the total and capture cross sections for 232Th resulting from a set of average resonance parameters. The average parameters are the average parameters based on our evaluation using SAMMY/FITACS and HARFOR, parameters obtained by L. Leal and presented at the last CRP meeting and parameters in the RIPL data base. We also used NJOY to process the evaluated file produced by SAMMYURR. Obviously below the first in-elastic channel the results are identical to those obtained with SAMMY/FITACS. However, above the threshold of the first in-elastic channel discrepancies are observed in capture as well as in total cross sections. When comparing the results obtained with Leal's and our parameters, we want to point out the difference in the scattering radius and the neutron strength functions. We show the difference in potential scattering contribution using these parameters. These differences can only be judged after the final analysis in the RRR and the total cross section at thermal energies
