222AC c  For a review of |a decay from oriented nuclei, see 1992Wo14.
222AC cA E,IA$Measured by 1964Mc21. Original energies have been increased
222AC2cA by 6 keV because of a change in the calibration energy of
222AC3cA the {+227}Pa |a from 6460 to 6465.8 {I3}, recommended by 1991Ry01.
222AC4cA The |a intensities are stated as approximate values by 1964Mc21,
222AC5cA and these add to 99, instead of expected 100.
222AC6cA Other measurements: 1951Me10, 1968Ha14, 1988Hu08.
222AC cA HF$The nuclear radius parameter r{-0}({+222}Fr)=1.5348 {I30}
222AC2cA is deduced from interpolation (or unweighted average) of radius
222AC3cA parameters of the adjacent even-even nuclides (2020Si16).
