158CE c  2017Wu04: The {+158}Ce nuclide was produced at the RIBF-RIKEN facility 
158CE2c  using the {+9}Be({+238}U,F) reaction at E=345 MeV/nucleon.  Two        
158CE3c  experiments, optimized for the transmission of {+158}Nd and {+170}Dy   
158CE4c  ions, were carried out with average beam intensities of 7 pnA and 12   
158CE5c  pnA, respectively. The identification of the nuclide of interest was   
158CE6c  made in the BigRIPS separator by determining the atomic number and the 
158CE7c  mass-to-charge ratio of the ion using the tof-B|r-|DE method. The      
158CE8c  reaction products were transported through the ZeroDegree Spectrometer 
158CE9c  and implanted into the beta-counting system WAS3ABi that was surrounded
158CEac  by the EURICA array comprising of 84 HPGe detectors. The typical       
158CEbc  implantation rate was ~~100 ions/s.  Measured: implanted ion-|b{+-}-t, 
158CEcc  implanted ion-|b{+-}-|g-t and implanted ions-|g-t correlations.
