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.

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.
