International Evaluation Cooperation Task 1.1: Intercomparison of Evaluated Files for 52Cr, 56Fe, and 58Ni

The cross sections and energy and angular distributions in the JENDL-3, JEF-2/EFF-2, and ENDF/B-VI evaluations for 52Cr, 56Fe, and 58Ni are compared graphically. The purpose is to understand the reasons for observed discrepancies among the evaluations, and to suggest recommendations for improvements. The accomplishments to date are presented.
