Thermal neutron cross-sections, resonance-parameters,
resonance integrals
ENDF-formatted libraries
Recent values of thermal neutron
cross-sections and resonance integrals are in the data
libraries BROND-2, CENDL-2, ENDF/B-6, JEF-2, JENDL-3
where, however, these values must be computed, for example
with the code series LINEAR, RECENT, INTER. For JENDL-3
these values are tabulated in the report JAERI-M-90-099
pages 461-486. For the JENDL-3 Fission Product Library
see the report JAERI-M-92-077 pages 453-488.- Note
however, that the new version, JENDL-3.2, contains revised
data for many nuclides.
JEF-2.2 INTER
From the JEF-2.2 point-data file tables of
important cross-section values have been derived by the
code INTER, including all cross-section values for 0.0253
eV, thermal Maxwellian, fission spectrum, 14 MeV, plus
resonance-integrals and thermal g-factors. Available on
tape or diskette.
JEF Report 14
For the ENDF-formatted data libraries JEF-2.2,
ENDF/B-6 (after the 93 update), JENDL-3.2, BROND-2 and
CENDL-2, this report lists the following quantities:
- 0.0253 eV cross-sections
- thermal Maxwellian average cross-sections
- resonance-integrals
- fission spectrum average cross-sections
- 14.0 MeV cross-sections.
The report is available from the
NEA Data Bank.
