|Abstract:||Work is reported here on the process and present results of an international evaluation of the neutron cross section standards. The evaluations include the Hn,n, 3Hen,p, 6Lin,t, 10Bn, 10Bn,1, 197Aun,235Un,f, and 238Un, f standard reactions as well as the 238Un, and 239Pun,f reactions. This evaluation was performed to include new experiments on the standards that have been made since the ENDF/B-VI evaluation was completed and to improve the evaluation process. Evaluations have been completed for the 6Lin,t, 197Aun,and 238Un, cross sections. Also below 20 MeV the Hn,n, 235Un,f, 238Un,f and 239Pun,f cross sections are completed. Many of the cross sections being evaluated are used in neutron dosimetry for fluence determination. The general trend observed for the evaluations is an increase in the cross sections for most of the reactions from fractions of a percent to several percent compared with the ENDF/B-VI results.|
