Analysis of the 4d9-(4d86p + 4p54d10) transitions of Sb VII and the strongest transitions of the 4d9-4d84f array of Sb VII and Te VIII

The spectra of antimony and tellurium were photographed in the 100-200 A region on grazing incidence spectrographs at Moscow, Russia and NIST, U.S.A. laboratories. The 4d9-[4d86p + 4p54d10] transition array of Sb VII was analyzed. 31 levels in Sb VII were established. 41 new lines in Sb VII belonging to the 4d9-(4p54d10 + 4d86p) transition array have been classified. Seven lines each in Sb VII and Te VIII belonging to the 4d9-4d84f transition array have been classified. Parametric least-squares-fitted calculations involving configuration interaction have been carried out to interpret the spectrum satisfactorily. (orig.)
