These cross sections are calculated from JENDL4.0 at 300K.
The background color of each cell noted a cross section means the order of the crosssection value.
The unit of cross section, (b), means barns, and SI prefixes are used as following.
(kb) → 10^{3}(b), (mb) → 10^{−3}(b),
(μb) → 10^{−6}(b), (nb) → 10^{−9}(b).
MT is a number that defines a reaction type. For the relation between MT and reaction type, please see here or refer to the manual of ENDF formats.
Maxwellian Average :
where T denotes the temperature, and k_{B} the Boltzmann constant.
The upper and lower limits of integration, E_{L} and E_{U}
are set to 10^{−5} eV and 10 eV, respectively.
Resonance Integral :
with E_{L} = 0.5 eV and E_{U} = 10 MeV.
U235 Thermal FissionNeutron Spectrum Average (Fiss. Spec. Average) :
with E_{L} = 10^{−5} eV and E_{U} = 20 MeV.
The parameters a and b are 0.988 MeV and 2.249 MeV^{−1}, respectively.
