摘要:
The hyperfine structures in the spectrum of Pb III, excited by an electrodeless discharge, have been studied by means of a 21 ft. concave grating. The hyperfine structure patterns lead to anI-value ofand ag(I) factor of 1.2 for the odd isotope, in agreement with the results of previous workers. The isotope shifts between the even isotopesandare in agreement with Breit's theoretical interpretation, and amount to 0.5 cm.−1for each 6selectron. The fact that the deep terms in the spectrum of Pb III are rather completely known permits an attempt to be made at a careful comparison between experiment and theory.
