Abstract: A new evaluation of the neutron cross section standards was recently completed. The results of this work became the standards for the new ENDF/B-VII library. This evaluation was performed to include new experiments on the standards that have been made since the ENDF/B-VI standards evaluation was completed and to improve the evaluation process. The evaluations include the H(n,n), 6Li(n,t), 10B(n, alpha), 10B(n,alpha1 gamma), 197Au(n, gamma), 235U(n,f), and 238U(n,f) standard reactions. Evaluations were not done for the 3He(n,p) and C(n,n) standards which were carried over from ENDF/B-VI. The need for standards above 20MeV led to the extension of the 235U(n,f) and 238U(n,f) cross sections to 200MeV. In addition evaluations were produced for the non-standard 238U(n,gamma) and 239Pu(n,f) reactions. Results of this work and comparisons with previous evaluations are presented.
