253CF c  The high-resolution laser spectroscopy performed to determine the      
253CF2c  spectral linewidth in the order of 180 MHz at the RISIKO mass          
253CF3c  separator at Johannes Gutenberg University Mainz (JGU). The            
253CF4c  californium sample used was originally produced at ORNL in the HFIR    
253CF5c  in 2019, was irradiated in 2021 with thermal neutrons in Grenoble and  
253CF6c  was returned to JGU for separation of individual actinide elements     
253CF7c  and subsequent laser spectroscopy. The separation of californium from  
253CF8c  einsteinium was performed at the Department of Chemistry's Triga site  
253CF9c  at Mainz. The sample was dissolved in 0.1 min nitric acid, the         
253CFac  californium isolation was performed and eluted fraction was            
253CFbc  transferred on two zirconium foils and evaporated to dryness. Based    
253CFcc  on the measured isotope ratio {+252}Cf/{+253}Cf, the amount of         
253CFdc  {+253}Cf was evaluated as 5|*10{+7} atoms. The samples were inserted   
253CFec  into the atomizer tube and the high-resolution laser spectroscopy      
253CFfc  measurement was performed at the RISIKO mass separator. Three          
253CFgc  different resonant two-step ionization schemes were investigated.      
253CFhc  Measured: Hyperfine spectra, isotope shift respect to the {+250}Cf.    
253CFic  Deduced: Hyperfine structure (HFS) parameters, magnetic moment |m and  
253CFjc  quadrupole moment Q. Comparison with model calculations.

253CF c  The isotope shifts for 420 nm, 417 nm and 410 nm optical transitions   
253CF2c  are |d|n{-420}=17470 MHz {I50}, |d|n{-417}=-16052 MHz {I20} and        
253CF3c  |d|n{-410}=-15230 MHz {I75} compared with reference isotope {+250}Cf.
