207RA c  2021Ni08: {+206}Ra was produced using {+159}Tb({+51}V,3n) reaction.    
207RA2c  The experiment was performed at the SHE-Mass-II facility jointly       
207RA3c  operated by RIKEN Nishina Center and KEK Wako Nuclear Science Center,  
207RA4c  within the RIKEN I|g Beam Factory. The primary beam {+51}V{+13+} was   
207RA5c  delivered by the RILAC-II linear accelerator and injected into the     
207RA6c  RIKEN Ring Cyclotron and accelerated to 306.0 MeV. The primary beam    
207RA7c  impinged on a rotating target wheel with 16 {+159}Tb targets backed    
207RA8c  with Ti foils. 12.5-|mm Al foil energy degraders were mounted on the   
207RA9c  target wheel upstream of the targets. The primary beam energy after    
207RAac  the energy degrader was 219.1 MeV at the target center. The            
207RAbc  fusion-evaporation product ions were separated from the primary beam   
207RAcc  by the gas-filled recoil ion separator GARIS-II. Multireflection time  
207RAdc  of flight-Mass Spectrometer (MRTOF-ms) used for mass analysis. An      
207RAec  |a-tof detector placed at the end of MRTOF-ms, detected both ion       
207RAfc  implantation and subsequent |a-decay events from implanted ions. Two   
207RAgc  measurement runs were performed. Run 1 was 6 hours in duration and     
207RAhc  Run 2 was 1 hour in duration, wherein ions made an extra lap in the    
207RAic  MRTOF to confirm identification. Measured tof spectra, m/q, E(|a) and  
207RAjc  %|a of {+207m}Ra. Deduced T{-1/2}, mass excess, E{-x}({+207m}Ra) and
