211AT c 1984Sc25: observed alpha from {+208}Pb({+11}B,4n) E=66 MeV.
211AT c Target: >99% enriched {+208}Pb.
211AT2c Measured E|g, I|g, E|a, |g|g- and |g|a coin, |g|g(t), pulsed-beam,
211AT3c |g(|q). Deduced |a-particle branches.
211AT c 1984De16: observed alpha from {+208}Pb({+11}B,4n) E=58,62 MeV.
211AT2c E|g, I|g, E|a, ce, |g|g- and |g|a coin, |g|g(t), g factors.
211AT3c Deduced |a-particle branches
211AT cA E$ Long-range |a particle group from 1440-keV level in {+215}Fr.
211AT cA IA$ From |a|g-coin and relative to the total number
211AT3cA of |a particles in the spectrum.
211AT cA HF$ r{-0}({+211}At=1.5365 {I55}; interpolated value deduced from
211AT2cA r{-0}({+210}Po)=1.532 {I6}, r{-0}({+212}Rn)=1.541 {I5} (1998Ak04).
215FR P 1440.0 1 (19/2)- 4 NS 2 9540 7
215FR cP E,J$ From Adopted Levels of {+215}Fr in ENSDF database
215FR cP T$ From |g|g(t) (1984De16); this half-life may correspond to
215FR2cP 1440 or 1573 level. However, half-life of 1573 level is measured
215FR3cP as 3.5 ns {I14} in 1984Sc25
215FR cP QP$ From 2012Wa38
211AT N 0.047 4
211AT cN BR$ %|a=4.7 {I4} (deduced by evaluators from I|a(10740)/I|a(total)=
211AT2cN 4.1% {I3} (1984Sc25), and renormalizing g.s. |a branch from 87.7%
211AT3cN to 100%. It is assumed by the evaluators that 1984Sc25 have corrected
211AT4cN for 78% detection of the ground state |a branch in |a|g-coin spectrum.
211AT5cN Other: I(10789|a)/I(9369|a)=1.5% (1984De16) is in disagreement
211AT L 0.0 9/2-
211AT A 10779 15 100 6.2E2 32
211AT cA E$ weighted average of 10740 {I30} (1984Sc25) and 10789 {I15}
