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: The report is available from the NEA Data Bank.

Thermal neutron cross-sections and resonance-parameters

See reports BNL-325 and the books "Neutron Cross-Sections" (Academic Press), Vol.1, containing thermal neutron cross-sections and resonance parameters. These books are not available from IAEA, and the corresponding data are not available on magnetic tape. Of these books the thermal neutron cross-section and resonance-integral data are available online from the NUDAT page or from the NDIS service.
