22Ne
22Ne is formed when 18O + α 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 22Ne: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Level scheme
Adopted levels of 22Ne 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 18O(α,γ)22Ne threshold (S = 9666.8 keV) and the top of the Gamow window at T9 = 0.2 (488 keV above it), with the resonance strengths ωγ EXFOR holds for them.
Looking for measured strengths…
| E (keV) | E_r (keV, c.m.) | Jπ | T½ or Γ | ωγ measured |
|---|---|---|---|---|
| 9725 ± 10 | 58.18 | (3-) | – | … |

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