An investigation is made of the spectroscopic isotope shift in the Pb II visible spectrum by using enriched isotopes. The isotope structure of Pb/sup 204/ , Pb/sup 206, and Pb/sup 208/, and the hyperfine structure of Pb/sup 207/ in the transitions; 15,011 cm/sup -1/ (6s/sup 2/7s /sup 2/S/sub 1/2/--6s/sup 2/ 7p/sup 2/ P/sub 1/2 E), 17,824 cm/sup -1/ (6s/sup 2/7p /sup 2/S/sub 1/2-6s/sup 2/7p /sup 2/ P/sub 3/2 deg /), 18,032 cm/sup 1/(6s/sup 2 7p /sup 2P/sub 3/2 deg deg /) are analyzed with a Fabry-Perot interferometer crossed with a constant-deviation Hilger spectrograph. The samples are excited in a Schuler hollow cathode discharge tube. Spacings between consecutive even isotopes, (205-206), 208 (207c.g.-208), and the ratios (204--206)/(206--208), (206--207c.g.)/(207c.g.-- 208) are given.
