210Bi

210Bi is formed when 209Bi + 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 210Bi: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Every EXFOR reaction that forms ²¹⁰Bi: entrance pair (rows) and the quantities measured (columns), with the energies covered.

Resonances in the window

Levels between the 209Bi(n,γ)210Bi threshold (S = 4604.6 keV) and the top of the Gamow window at T9 = 0.09 (50 keV above it), with the resonance strengths ωγ EXFOR holds for them.
