This tool is to retrieve information on resolved resonances, which is based on the resolved resonance parameters in resonance region adopted for all nuclides in JENDL-4.0.

[Res. Energy (Er)] input

Lower and/or upper boundary of “resonance energy” can be input in [eV]. These inputs are not necessary when a search by resonance energy is not required.

[Peak CS (σ-peak)] input

Lower and/or upper boundary of “resonance peak cross section” can be input in [barn]. These inputs are not necessary when a search by resonance peak cross section is not required.

[Atomic # (Z)] input

Lower and/or upper boundary of “atomic numbers” can be input. These inputs are not necessary when a search by atomic number is not required.

[Mass # (A)] input

Lower and/or upper boundary of “mass numbers” can be input. These inputs are not necessary when a search by mass number is not required.

[Sorting] selection

Sorting of search result in ascending or descending order can be selected from resonance energy or resonance peak cross section. By default, data are sorted by resonance energy in ascending order.

[Show result] button

Information on resolved resonances is shown as table data by clicking the “Show Result” button. The corresponding information will appear, if the above settings are specified.

(From left to right) Resonance energy (Er in [eV]), angular momentum (L), spin (J), neutron width (Γn in [eV]), gamma width (Γγ in [eV]), fission width (Γf1, Γf2 in [eV]), peak cross section (σ-peak in [barn]), capture kernel (Kγ = gΓnΓγ / (Γn + Γγ) in [eV]), target nuclide with link to the resolved resonance data in JENDL-4.0 (Target), link to Figure of cross sections (Fig1) on the JENDL-4.0 web page (Fig).

“Link to data files” is link to resonance parameter files of nuclides contained in JENDL-4.0. In the files, upper boundary energy of resolved resonance region applied to JENDL-4.0 is described on the first line with a symbol “$ EHIGH:”, and resonance energy [eV], angular momentum, spin, neutron width [eV], gamma width [eV], fission width (Γf1, Γf2) [eV] from left to right below the first line.
