240CM cA E$The evaluator has considered values from studies where two |a
240CM2cA decays were observed, namely 1996Ma72 and 1967Si08.  Energies from
240CM3cA other studies where only a single |a decay was observed: 7210 keV
240CM4cA {I20} (1973Es02), 7207 keV {I2} (1967Fi04), 7170 keV {I20} (1956Ch43).
240CM cA IA$|a intensity per 100 |a decays, given as recommended by 1991Ry01
240CM2cA from the intensity ratio of I|a(7214|a)/I|a(7174|a)=3.0 {I3},
240CM3cA measured by 1967Si08. The increased uncertainty, following evaluation
240CM4cA by 1991Ry01, reflects probable contributions from other sources.
240CM cA HF$The nuclear radius parameter r{-0}({+240}Cm)=1.4981 {I40} is
240CM2cA deduced by assuming HF=1.0 for the ground-state to ground-state alpha
240CM3cA decay branch.
240CM c  $1950Th56, 1950Th57, and 1951Gh23 report on radioactivity initially
240CM2c  assigned to {+244}Cf, but which was later reassigned to {+245}Cf in
240CM3c  1956Ch43.
