Abstract: (Elsevier)
Previous laser-spectroscopic studies of the hyperfine structure splittings and isotope shifts of the (6p 2 3 P 0 -6p7s 3 P 1 ; 283.3 nm) PbI resonance line have been extended to further radioactive Pb nuclides: 196, 197, 197m, 211, 214 Pb Using an improved theoretical result for the specific mass shift, we recalibrate the isotope shifts of the full series ( A = 196–214) of measured isotope shifts in terms of the nuclear parameter and determine the odd-even staggering parameters. The variation of the nuclear charge radii of the Pb nuclides exhibits distinct shell effects, and the odd-even staggering shows a conspicuous trend, being more pronounced for neutron-deficient Pb isotopes.
