As a light source the electrodeless discharge tube was used. The high resolution spectral apparatus consisted of a silver coated Fabry–Perot etalon and a grating spectrograph combined with a CCD camera used as a detector. In the analysis of the spectra a computer simulation technique was used. The experiments with the isotope 207Pb yielded the hyperfine structure splitting constant A for the 3P1 level of the 6s26p2 ground configuration. In the experiment with natural lead the isotope shifts between four stable isotopes (204, 206, 207, 208) were measured.}, title={Hyperfine structure and isotope shifts in 461.9 nm forbidden line of Pb I}, type={artykuł}, keywords={optyka, hyperfine structure, isotope shift, forbidden lines, lead}, }
