23Ne

23Ne is formed when 22Ne + 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 23Ne: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Resonances in the window

Levels between the 22Ne(n,γ)23Ne threshold (S = 5200.7 keV) and the top of the Gamow window at T9 = 0.3 (58.2 keV above it), with the resonance strengths ωγ EXFOR holds for them.
