20Ne

20Ne is formed when 19F + p or 16O + 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 20Ne: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Resonances in the window

Levels between the 19F(p,α)16O threshold (S = 12843 keV) and the top of the Gamow window at T9 = 0.05 (90.7 keV above it), with the resonance strengths ωγ EXFOR holds for them.

ENSDF lists no level in this window.

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