Description

Comparisons of evaluated fission cross sections for 235U in JENDL-3.3 and ENDF/B-VI are carried out. The comparisons are made for both the differential and integral data. The fission cross sections as well as the fission ratios are compared with the experimental data in detail. Spectrum averaged cross sections are calculated and compared with the measurements. The employed spectra are the 235U prompt fission neutron spectrum, the 252Cf spontaneous fission neutron spectrum, and the neutron spectrum produced by a 9Be(d, xn) reaction. For 235U prompt fission neutron spectrum, the ENDF/B-VI evaluation reproduces experimental averaged cross sections. For 252Cf and 9Be(d, xn) neutron spectra, the JENDL-3.3 evaluation gives better results than ENDF/B-VI. (author)
