Abstract
The sixth spectrum of antimony (Sb VI) and the seventh spectrum of tellurium (Te VII) have been photographed in the region 600–2100 Å on a 10.7 m normal incidence spectrograph using a triggered spark source. All levels of the 4d95s and 4d95p configurations of Sb VI and Te VII given in Atomic Energy Levels Volume III have been found to be completely wrong. New level values of the levels of both configurations for these spectra have been established. Thirty-four lines have been classified in the Sb VI spectrum and thirty-three in the Te VII spectrum. The new analyses have been confirmed by parametric level fitting calculations and by intensity calculations of the transitions. A comparison between the least-squares fitted (LSF) parameter values and the Hartree–Fock (HF) parameter values in the Ag II–Te VII sequence is given.
