156CE c  2017Wu04: The {+156}Ce nuclide was produced at the RIBF-RIKEN facility 
156CE2c  using the {+9}Be({+238}U,F) reaction at E=345 MeV/nucleon.  Two        
156CE3c  experiments, optimized for the transmission of {+158}Nd and {+170}Dy   
156CE4c  ions, were carried out with average beam intensities of 7 pnA and 12   
156CE5c  pnA, respectively. The identification of the nuclide of interest was   
156CE6c  made in the BigRIPS separator by determining the atomic number and the 
156CE7c  mass-to-charge ratio of the ion using the tof-B|r-|DE method. The      
156CE8c  reaction products were transported through the ZeroDegree Spectrometer 
156CE9c  and implanted into the beta-counting system WAS3ABi that was surrounded
156CEac  by the EURICA array comprising of 84 HPGe detectors. The typical       
156CEbc  implantation rate was ~~100 ions/s.  Measured: implanted ion-|b{+-}-t, 
156CEcc  implanted ion-|b{+-}-|g-t and implanted ions-|g-t correlations.
