In I isoelectronic sequence: wavelengths and energy levels for Xe VI through La IX

Journal Article · · J. Opt. Soc. Am. B: Opt. Phys.; (United States)
Spectra of Xe, Cs, Ba, and La produced with a high-voltage spark discharge were observed photographically with the National Bureau of Standards 10.7-m normal- and grazing-incidence spectrographs. Identified lines of the In I isoelectronic sequence were used to determine the energy levels of the 5s /sup 2/5p, 5s5p/sup 2/, 5s/sup 2/5d, and 5s/sup 2/6s configurations. Their interactions with unobserved configurations that include a 4f electron are discussed. Fitted values of the radial energy integrals were determined from the known levels.
