63Ni
63Ni is formed when 62Ni + 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 63Ni: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Level scheme
Adopted levels of 63Ni 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 62Ni(n,γ)63Ni threshold (S = 6837.8 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.
