Abstract

The isotope shift in the 283.3-nm resonance line of mass-separated radioactive ²⁰²Pb was measured by absorption spectroscopy with the use of our 9.1-m focal-length Czerny–Turner spectrometer. The value of the shift, relative to ²⁰⁸Pb, is −208(3) × 10⁻³ cm⁻¹. A signal-averaging scanning technique was used to record the spectrum. Isotonic comparisons with the relative isotope shifts in mercury and thallium indicate a possible effect on the isotope shift of the unpaired proton in thallium.
