211AT c 1971Ma36: {+204}Hg({+11}B,4n|g), {+208}Pb({+7}Li,4n|g) E=41 MeV, and
211AT2c {+209}Bi(|a,2n|g) E=34 MeV. Measured: E|g, I|g, Ice, |g|g, excit
211AT3c (delayed and in-beam); (beam)(|g)(t); |g|g(t); (beam)(|g)(|q) (in
211AT4c beam); |g(|q,H,t) (with a liquid {+204}Hg target). Comparison with
211ATxc shell-model calculations
211AT c 2009Ba28: {+9}Be({+238}U,X) E=1 GeV/nucleon, {+211}At isomer populated
211AT2c and separated in fragmentation reaction using FRS at GSI facility,
211AT3c measured |g rays using RISING array of Ge detectors. Following |g rays
211AT4c in spectral figure 2 of the paper: 204, 253, 435, 511, 689, 1067, 1535.
211AT5c All the |g rays are in agreement with those from 1971Ma36

211AT cG RI$Values given are delayed photon intensities from the 4.2-|ms isomer.
211AT2cG The reaction for these intensities is not stated by 1971Ma36.
211AT3cG The authors also give prompt to delayed intensity ratios for
211AT4cG reactions with 34-MeV |a and 41-MeV {+7}Li beams.
211AT cG CC$Adjusted by evaluator to give |a(L)(253.5|g)=0.0920 (theory, E2).
