Evaluations of the /sup 58/Fe(n,. gamma. )/sup 59/Fe, and /sup 54/Fe(n,p)/sup 54/Mn reactions for the ENDF/B-V dosimetry file. [E < 15 MeV]
A generalized least-squares adjustment procedure was used to evaluate two important dosimetry reactions for the ENDF/B-V files. Calculations for the cross section adjustments were made with the computer code FERRET, where input data included both integral and differential experimental data results. For the /sup 54/Fe reaction, important ratio measurements were renormalized to ENDF/B-V evaluations of /sup 235/U(n,f), /sup 238/U(n,f), and /sup 56/Fe(n,p). A priori curves which are required for the calculations were obtained using Hauser-Feshbach calculations from the codes NCAP (/sup 58/Fe) and HAUSER-5 (/sup 54/Fe). Covariance matrices were also calculated and are included in the evaluations. 8 figures, 1 table.
