Title: Characterization of several ultraviolet--visible emission lines from a lead hollow-cathode lamp

Journal Article · · J. Opt. Soc. Am. B: Opt. Phys.; (United States)

The Fourier-transform spectra (0.015-cm/sup /minus/1/ resolution) of thenonresonant 405.8-, 368.4-, and 364.0-nm lines and the resonant 283.3-nm linefrom a lead hollow-cathode lamp are reported. The splittings for the variousisotopic and nuclear hyperfine transitions for all four lines are found to beconsistent with previous measurements and assignments. At the recommended lampoperating current of 4 mA, all peak shapes within all four lines studied weresatisfactorily fitted with Gaussian functions corresponding to the same Dopplertemperature of 750+-30 K, indicating no significant self-absorption of the283.3-nm resonant line. At a much-elevated lamp current the peaks for thenonresonant lines are increased in intensity and slightly broadened, whereas thepeaks for the resonant line have approximately the same intensity as at 4 mA butare no longer Gaussian shaped.
