212BI c 1994Li10: {+224}Ac activity produced by bombarding targets of
212BI2c {+232}Th with 200-MeV protons followed by mass separation. Sources of
212BI3c {+216}At were produced in secular equilibrium with {+220}Fr and
212BI4c {+224}Ac. Measured E|a, I|a, E|g, I|g, |a|g coin, ce, |a-ce coin,
212BI5c ce-|g coin using Ge detectors for |g rays and Si(Li) for conversion
212BI6c electrons.
212BI cA E$From 1994Li10, decreased by 2 keV so E|a(g.s.)=7802 keV, except
212BI2cA where noted.

212BI cA IA$From 1994Li10, except where noted otherwise.
212BI cA IA(E)$I|a(7610|a+7560|a)=0.2, estimated by evaluator from decay
212BI2cA scheme.

212BI2cG from this dataset, supporting measurements are given in the comments.
212BI cL E$From a least-squares fit to |g-ray energies for |DE<1 keV and from
