The activation cross sections were evaluated for fission product nuclides of ~(144,141,142,144)Ce below 20 MeV to provide data for reactor design. Evaluation was made on the basis of experimental data up to 1998 and nuclear mode calculation. The experimental data for ~(140,142)Ce(n, 2n), ~(140,142)Ce(n,γ) from threshold energy to 20 MeV and ~(140,142)Ce(n, p), ~(142)Ce(n,α)reactions at some energys points were adopted in this work. The evaluated data of ~(140,141,142,144)Ce were compared with other evaluated data from ENDF/B-6, JENDL-3 and BROND-2 Libraries.
The activation cross sections were evaluated for fission product nuclides of ~ (144,141,142,144) Ce below 20 MeV to provide data for reactor design. Evaluation was made on the basis of experimental data up to 1998 and nuclear mode calculation. The experimental data for ~ (140,142 Ce (n, 2n), ~ (140,142) Ce (n, γ) from threshold energy to 20 MeV and ~ (140,142) Ce (n, p) points were adopted in this work. The evaluated data of ~ (140,141,142,144) Ce were compared with other evaluated data from ENDF / B-6, JENDL-3 and BROND-2 Libraries.
