218FR c  1982Bo04: measured E|a
218FR c  1972Es03: measured E|a, I|a, half-life of decays of {+222}Ac and
218FR2c  {+218}Fr. Deduced hindrance factors.
218FR c  1964Mc21: measured E|a, I|a
218FR c  Other: 1991Ga28: |a|a correlations from successive |a decays
218FR cA IA$|a intensity per 100 |a decays. These I|a data are the values
218FR2cA recommended by 1991Ry01 from I|a measured by 1964Mc21.
218FR cA HF$The nuclear radius parameter r{-0}({+218}Fr)=1.5497 {I30}
218FR2cA is deduced from interpolation (or unweighted average) of radius
218FR3cA parameters of the adjacent even-even nuclides.

218FR2cA 1972Es03 and 1964Mc21. The original energies were changed because of
218FR3cA changes in calibration energies used. The original energies and the
218FR4cA changes (+ for increased energies, and - for decreased E|a) are
218FR5cA 7013 {I2} (-4.4) (1982Bo04), 7010 {I20} (+1.4) (1972Es03), 6998 (-1.6)
