160PM c  2022Ki23: {+160}Pm nuclide was produced at the RIBF-RIKEN facility     
160PM2c  using the {+9}Be({+238}U,F),E({+238}U)=345 MeV/nucleon, followed by    
160PM3c  separation of fission fragments by measuring the energy loss (|DE),    
160PM4c  magnetic rigidity (B|r) and time-of-flight (tof) of the ions using     
160PM5c  the BigRIPS separator, multisampling ionization chambers (MUSIC),      
160PM6c  and parallel-plate avalanche counters (PPACs), and plastic             
160PM7c  scintillators. The radioactive ions were implanted in the Advanced     
160PM8c  Implantation Detector Array (AIDA) consisting of a stack of six        
160PM9c  double-sided silicon strip detectors (DSSSDs), and centered in the     
160PMAc  BRIKEN neutron detector consisting of 140 {+3}He-filled proportional   
160PMBc  counters embedded in a large polyethylene moderator matrix. For |g     
160PMCc  and n|g-coin detection, two CLARION-type clover HPGe detectors were    
160PMDc  used, but |g data were not analyzed in the present experiment. Measured
160PMEc  (implanted ions)(|b{+-}) correlations, and                             
160PMFc  (implanted ions)(|b{+-})(neutron) correlations. Deduced half-life and  
160PMGc  %|b{+-}n for the decay of {+160}Pm.
