25Al
25Al is formed when 24Mg + p 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 25Al: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Level scheme
Adopted levels of 25Al 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 24Mg(p,γ)25Al threshold (S = 2271.4 keV) and the top of the Gamow window at T9 = 0.08 (150 keV above it), with the resonance strengths ωγ EXFOR holds for them.

| E (keV) | E_r (keV, c.m.) | Jπ | T½ or Γ | ωγ measured |

| 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.
