224RA c 1977Ku15 (also 1977Ku25): measured E|g, I|g, |g|g-coin using Ge(Li)
224RA2c detectors. Deduced levels, J, |p, half-life, |a hindrance factors
224RA c 1984Ge07: measured I|g, absolute I|g using 4|p|a-|g counting system.
224RA2c Precise E|g values were not measured in this work
224RA c 1970Ba20: measured E|a, I|a using a magnetic spectrograph. Deduced
224RA2c levels, J, |p. See also 1976BaZZ
224RA c 1989Po19: measured |g|g-coin, |a|g(|q), ce, total-conversion
224RA2c coefficients from |a|g-coin data
224RA c Others:
224RA c 1973He13: measured g factor of first 2+ state
224RA c 1970SpZW: measured subshell ratios
224RA c 1968Du06, 1966Co40: measured total-conversion coefficient from
224RA2c |a|g-coin data
224RA c |a measurements: 1971Gr17, 1953As31, 1949Ro02. Evaluation: 1991Ry01
224RA c |g ray measurements: 1982Sa36, 1974HeYW, 1973Ta25, 1972DaYV, 1957St92,

224RA c |a|g(|q) measurements: 1954St02, 1953Ba07, 1951Be42
224RA c 1982Sa36: measured I|g for four |g rays. The values are systematically
224RA2c lower than in 1977Ku15 and 1984Ge07, thus not used here
224RA c The decay scheme is from 1977Ku15
224RA cA E$Data for the ground-state and 84-level branches are from 1991Ry01
224RA2cA evaluation. Others are from 1970Ba20, but increased
224RA3cA by 2 keV by the evaluators to account for changes in calibration as
224RA4cA deduced from a comparison of authors' values for the two strong
224RA5cA branches with those of 1991Ry01 evaluation
224RA cA IA$From I(|g+ce) imbalance at each level, unless stated otherwise
224RA cA HF$HF(5423.15|a)=1.0 yields r{-0}({+224}Ra)=1.53389 fm {I32}, same
224RA2cA r{-0} in 2020Si16 evaluation.
224RA cG E$From 1977Ku15 unless otherwise noted
224RA cG E(D)$The value in 1977Ku25 has been adjusted by the evaluators for
224RA2cG change in calibration of {+198}Au line from 411.794 keV {I7} (used
224RA3cG by 1977Ku25) to 411.80205 keV {I17} recommended by 2000He14.
224RA cG RI$Relative to 100 for the 84|g. Values for the strong lines
224RA2cG (>1) are from 1984Ge07. Others are from 1977Ku15.
224RA cG M(F)$From an intensity balance at the 216 level, using
224RA2cG I|a(5211|a)=0.36 (1970Ba20), both the 131|g and 216|g must be E1.
