Abstract

Hyperfine structure of several lines in neutral and singly ionized lead have been measured. The discharge tube containing metallic isotope ²⁰⁷Pb was used as a light source. The high resolution spectral apparatus consisted of a silver coated Fabry-Perot etalon and a grating spectrograph combined with CCD camera used as a detector. In the analysis of the spectra we used a computer simulation technique. Our experiment yields the following hyperfine splitting constants A: A(6p² ¹D₂)=(20.69 ±0.21) mK, A(6p² ³P₂)=(91.37±0.34) mK A(6p7s ¹P₁)=(16.45±0.95) mK, A(6p7s ³P₁)=(293.93±0.56) mK, A(6p6d ³F₂)=(103.22±0.31) mK, A(6p6d ³F₃)=(69.12±0.28) mK, A(6p8s ³P₁)=(202.04±0.48) mK, A(6p8p ³P₁)=(224.26±1.37) mK, A(6p8p ³D₂)=(108.02±1.14) mK, A(6p7d ³D₁)=(-100.86±0.53) mK for the levels of PbI and A(6s² 7s ²S_1/2)=(352.1±1.7) mK, A(6s² 7p ²P_3/2)=(13.6±1.3) mK, A(6s² 7p ²P_1/2)=(70.8±1.1) mK for the levels of Pb II. Our results are compared with recent theory and other experiments.
