86Kr
86Kr is formed when 85Kr + n fuse. Its levels just above each threshold are the resonances that set those reactions' rates.
Channels and what has been measured
Every EXFOR reaction that forms 86Kr: entrance pair (rows) and the quantities measured (columns), with the energies covered.
| Reaction | Datasets | σ | MACS | other | Fitted in evaluation |
|---|---|---|---|---|---|
| 85Kr(n,γ)86Kr | 7 | 125 meV | 430 keV | 2 |
Level scheme
Adopted levels of 86Kr from ENSDF, with the particle thresholds and the Gamow window of the selected channel drawn across them.
- level in the window with a measured ωγ
- level in the window with no ωγ in EXFOR
- Jπ in parentheses or in italics is tentative.
Resonances in the window
Levels between the 85Kr(n,γ)86Kr threshold (S = 9856.7 keV) and the top of the Gamow window at T9 = 0.09 (50 keV above it), with the resonance strengths ωγ EXFOR holds for them.

A strength is matched to a level when its resonance energy plus the threshold lies within max(3 keV, 3σ) of the level energy.
