212RN cA HF$r{-0}({+212}Rn)=1.543 {I4} is calculated by evaluators
212RN2cA from HF(9349|a)=1.0.
212RN c  1973No09: {+216}Ra activity produced in {+208}Pb({+12}C,4n) reaction
212RN2c  with E({+12}C)=79 MeV. Measured E|a, I|a, |a(t), excitation function
212RN3c  using thin Si detector.

212RN cN BR$|e decay branch for {+216}Ra was estimated by 1986Ma45 as
212RN2cN <1|*10{+-8}% from log| {Ift} value for a possible branch to the
212RN3cN ground state of {+216}At.
