Abstract
Isotope shifts and hyperfine structures have been determined for the three near-ultraviolet transitions 405.8 nm 368.3 nm and 364.0 nm in stable isotopes of Pb I using the technique of saturated absorption spectroscopy in a sputtered vapor. The isotope shifts for these transitions and the magnetic hyperfine interaction constants for the metastable levels are the first Doppler-free determinations for these systems reported in the literature to our knowledge. Combined with experimental data, previously given in the literature, and pseudorelativistic Hartree-Fock estimates, the field shifts (FS’s) of seven relevant configurations are deduced: and referred to The hyperfine-structure integrals deduced from the experimental A factors for p electrons of the ground configuration are in good agreement with results of ab initio calculations.
