143I  c  2020Wu04: {+143}I nuclide produced at the RIBF-RIKEN facility in       
143I 2c  {+9}Be({+238}U,F) reaction at E=345 MeV/nucleon and an intensity of    
143I 3c  5pnA. Identification of fission fragments of interest was made based on
143I 4c  time-of-flight (tof), magnetic rigidity (B|r), and energy loss (|DE)   
143I 5c  using the BigRIPS spectrometer, determining atomic Z and mass-to-charge
143I 6c  ratio A/Q, where Q=charge state of the ions. The separated nuclei      
143I 7c  were implanted at a rate of 100 ions/s in the beta counting system     
143I 8c  of the Wide range Active Silicon-Strip Stopper Array for Beta and      
143I 9c  ion detection (WAS3ABi), which included a stack of five Double Sided   
143I Ac  Silicon Strip Detectors (DSSSDs). The WAS3ABi setup was surrounded     
143I Bc  by Euroball RIken Cluster Array (EURICA) array of 84 HPGe detectors    
143I Cc  for |g detection. Half-life of the separated and implanted ions        
143I Dc  was determined by fitting the time distribution of |b(implants)- and/or
143I Ec  |b|g(implants)-correlated decay curves to the sum of activities of     
143I Fc  parent nuclei, daughter nuclei, grand-daughter nuclei, |b-delayed      
143I Gc  neutron daughter and grand-daughter nuclei, and a constant background.
