Evaluation of ⁵⁴Fe(n, 2n) Cross Sections and Their Covariance Data Below 20 MeV

Experimental data of ⁵⁴Fe(n, 2n) cross sections below 20 MeV were analyzed and evaluated with corrections and normalization. The data were processed in terms of a fitting by a spline code with the consideration of correlation errors. Also, the corresponding covariance matrices of the experimental data were constructed with the information on experimental errors and correlation errors.
