Abstract

The isotope shift (IS) in two visible lines of neutral lead involving transitions 6s² 6p7s ¹P₁-6s² 6p² ¹S₀ (λ5OO.6 nm) and 6s² 6p8s ³P₁-6s² 6p² ¹S₀ (λ520.3nm) have been measured using a Fabry-Perot interferometer. The isotope shifts between even isotopic pairs were found to be: v₂₀₈-v₂₀₆=73.3±0.9 mK and v₂₀₈-v₂₀₄=121.4±1.1 mK for 6p7s configuration and v₂₀₈-v₂₀₆=70.1±0.6 mK and v₂₀₈-v₂₀₄=135.7±0.8 mK for 6p8s configuration. The displacements of the centers of gravity of isotope 207 with respect to isotope 208 were determined to be v₂₀₈-v_{207 CG}=46.4±1.2 mK and v₂₀₈-v_{207 CG}=44.9±1.1 mK for 6p7s and 6p8s configurations, respectively.
