230PU cA HF$The nuclear radius parameter r{-0}({+230}Pu)=1.381 {I11} is
230PU2cA deduced by assuming HF=1.0 for the ground-state to ground-state alpha
230PU3cA decay branch.
230PU c  $2002CaZU: First observation of {+234}Cm using {+198}Pt({+40}Ar,4n)
230PU2c  reaction at GSI for several bombarding energies.  Determined decay
230PU3c  properties by analysis of correlated |a-decay chains.  Measured
230PU4c  E{-|a}, |a(t), |a|a.
230PU c  $2016Ka13: {+230}Pu produced through various decay paths originating
230PU2c  with {+234}Bk produced at RIKEN through the {+197}Au({+40}Ar,3n)
230PU3c  reaction.  Reaction products were attached to KCl aerosols and flowed
230PU4c  through a gas-handling system, then deposited on a rotating detector
230PU5c  apparatus to measure decay products.  Measured E{-|a}, |a|a and |a-SF
230PU6c  coincidence, time distribution between decay generations.

230PU cN BR$2002CaZU gives the measured ratio for |a/spontaneous-fission decay
230PU2cN of {+234}Cm as 94 {I9}/6 {I2}, but also assumes a 50%
230PU3cN electron-capture branch.  The evaluator has chosen to approximate the
230PU4cN |a-branching as |?40%.
