143XE c  2020Wu04: {+143}Xe nuclide produced at the RIBF-RIKEN facility in      
143XE2c  {+9}Be({+238}U,F) reaction at E=345 MeV/nucleon and an intensity of    
143XE3c  5pnA. Identification of fission fragments of interest was made based on
143XE4c  time-of-flight (tof), magnetic rigidity (B|r), and energy loss (|DE)   
143XE5c  using the BigRIPS spectrometer, determining atomic Z and mass-to-charge
143XE6c  ratio A/Q, where Q=charge state of the ions. The separated nuclei      
143XE7c  were implanted at a rate of 100 ions/s in the beta counting system     
143XE8c  of the Wide range Active Silicon-Strip Stopper Array for Beta and      
143XE9c  ion detection (WAS3ABi), which included a stack of five Double Sided   
143XEAc  Silicon Strip Detectors (DSSSDs). The WAS3ABi setup was surrounded     
143XEBc  by Euroball RIken Cluster Array (EURICA) array of 84 HPGe detectors    
143XECc  for |g detection. Half-life of the separated and implanted ions        
143XEDc  was determined by fitting the time distribution of |b(implants)- and/or
143XEEc  |b|g(implants)-correlated decay curves to the sum of activities of     
143XEFc  parent nuclei, daughter nuclei, grand-daughter nuclei, |b-delayed      
143XEGc  neutron daughter and grand-daughter nuclei, and a constant background.

143XEIc  (2019), KTUY+GT2, RHB+pn-RQRPA, and DF+CQRPA theoretical calculations.
