188BI2c reaction at E({+51}V)=230 MeV {I1} at the middle of target (enrichment
188BI2c 96.5%).The evaporation residues were separated by velocity filter SHIP
188BI3c at GSI, and implanted into position-sensitive silicon (PSSD) detector.
188BI4c FWHM=25-35 keV. Measured E|a, I|a, |g, |a|g coin. Gamma rays
188BI5c measured with a four-fold segmented Clover Ge detector. The |a
188BI6c spectrum is complicated by summing of the ce and |a signals in the
188BI7c PSSD detector. Analyzed correlated recoil-|a1-|a2 chains. GEANT
188BI8c Monte-Carlo simulations for ce+|a summing.
188BI cA HF$r{-0}=1.537 {I26}, obtained as average of r{-0} values
188BI2cA for the neighboring even-even nuclei:
188BI3cA r{-0}({+186}Pb)=1.510 {I2}, r{-0}({+188}Pb)=1.511 {I8} and
188BI4cA r{-0}({+190}Po)=1.590 {I11}, the later calculated by the evaluators
188BI5cA from T{-1/2}=0.78 ms {I16}, E|a=7700 keV {I10} and HF=1.0
