  "abstract": "Resonance laser ionization spectroscopy was conducted on stable chromium isotopes Cr50,52,53,54 using the RILIS laser ion source and the CRIS experimental apparatus at the ISOLDE/CERN facility. A unique titanium:sapphire laser-based three-step laser ionization scheme was developed to selectively and efficiently ionize and extract the Cr isotopes. Over 350 electronic transitions were observed, including several efficient transitions to autoionizing states. High-resolution spectroscopic measurements were performed with the 3d5(6S)4s a7S3→3d5(6S)4p z7P3 atomic ground-state transition to characterize the scheme and benchmark the performance of the CRIS setup. The isotope shifts δν50,52=−121(7)MHz, δν50,53=−137(6)MHz, and δν54,52=−14(6)MHz were measured, and the hyperfine structure parameter AS3=−82.64(16)MHz of Cr53 was extracted. A King plot analysis allowed reevaluation of the field shift F=−271(11)MHzfm−2 and mass shift M=105.3(30)GHzu factors of the transition with improved precision and accuracy. High-resolution measurements agree with the existing literature, supporting the accuracy and the reliability of the method for future studies involving radioactive isotopes.",
