Analysis of 5p65d-(5p65f+5p66p+5p55d2+5p55d6s) Transitions in TI XIII, Pb XIV, and Bi XV and Revised Wavelengths for 5p6 1So-5p55d(3/2, 5/2)

Abstract

Spectra of mercury, thallium, lead, and bismuth were photographed in the 70 A-250 A region on two grazing-incidence spectrographs with low-inductance vacuum sparks. About fifty-five 5p 6 5d-(5 P6 5f+5 P6 6p+5p55d 2 +5 P5 5d6s) transitions were identified in each of the spectra of TI xiii, Ph xiv, and Bi xv. T 5d 2 D3/2,5/2 fine-structure interval was determined as 29267 cm-' in TI xiii, 33195 cm-in Pb xiv, and 37370 cm-'1 in Bi xv. Hartree-Fock and least-squares-fitting parametric calculations were carried out to interpret the 5p 6 5f +5 P6 6p+5p55d 2 +5 P5 5d6s configurations in these three ions. Earlier identifications of the 5 P6 'So -5p 5 5d (3/2, 5/2), transitions Hg XIII, TI xiv, Pb xv, and Bi XVI were revised.
