Abstract

The spectra of antimony and tellurium have been photographed in the region 625–100 Å on 6.60 and 10.7 m spectrographs. The sources used were a sliding spark and a triggered spark. On the basis of these measurements the earlier analyses of these spectra hve been revised and extended. Parametric least-squares-fit calculations and Hartree-Fock calculations were carried out for the 4d⁹ and 4d⁸ 5p configurations. Comparison of these parameter values has been made for the spectra Ag iii to Te viii. The spectra of Sb vi and Te vii below 300 Å were extended and the ionization limits for Sb vi and Te vii have been found to be 795 340(8000) cm⁻¹ or 98.6(1.0) eV and 1 000 900(10 000) cm⁻¹ or 124.0(1.2) eV, respectively.
