131CD c  2015Lo04: {+131}Cd nuclide produced at RIBF-RIKEN facility in          
131CD2c  {+9}Be({+238}U,F) reaction at E=345 MeV/nucleon with an average        
131CD3c  intensity of 6|*10{+10} ions/s. Identification of {+131}Cd was made by 
131CD4c  determining atomic Z and mass-to-charge ratio A/Q, where Q=charge state
131CD5c  of the ions. The selectivity of ions was based on magnetic rigidity,   
131CD6c  time-of-flight and energy loss. The separated nuclei were implanted at 
131CD7c  a rate of 50 ions/s in a stack of eight double-sided silicon-strip     
131CD8c  detector (WAS3ABi), surrounded by EURICA array of 84 HPGe detectors.   
131CD9c  Correlations were recorded between the implanted ions and |b rays. The 
131CDAc  half-life of {+131}Cd isotope was measured from the correlated ion-|b  
131CDBc  decay curves and maximum likelihood analysis technique as described in 
131CDCc  2014Xu07 (Phys. Rev. Lett. 113, 032505). Comparison of measured

131CD2c  beam of 345 MeV/nucleon from the cascade operation of the RIBF complex 
131CD3c  of accelerators at RIKEN. Identification of {+131}Cd was made on       
131CD4c  the basis of magnetic rigidity, time-of-flight, and energy loss using  
131CD5c  the BigRIPS separator and ZeroDegree spectrometer. The separated nuclei
131CD6c  were implanted into a stack of six double-sided silicon-strip          
131CD6c  detectors (DSSDs) of the Advanced Implantation Detector Array (AIDA)   
131CD7c  for the detection of implanted ions and subsequent |b{+-} and          
131CD8c  |b{+-}-delayed neutrons. The AIDA array was surrounded by two clover   
131CD9c  HPGe detectors, and the BRIKEN neutron counter array of 140 {+3}He     
131CDAc  proportional counters embedded in a high-density polyethylene          
131CDBc  (HDPE) matrix. Measured and analyzed (implanted ions)-|b, and |b-n     
131CDCc  correlated events. The (implanted ions)|b-correlated events with the   
131CDDc  associated neutron multiplicity distributions were fitted using the    
131CDEc  maximum likelihood method, with the inclusion of probability density   
131CDFc  functions for decays of parent, subsequent all the daughter activities,
131CDGc  neutron background, and efficiencies of neutron and |b detectors.
