Analysis of the (5d(2)+5d6s)-5d6p Transition Arrays of Os VII and Ir VIII, andthe 6s (2)S-6p (2)P Transitions of Ir IX

摘要

The spectra of osmium and iridium were photographed in the 300 Angstroms to 1600Angstroms region on a 3 m normal incidence spectrograph using a triggered spark source. The (5d2 + 5d6s)-5d6p transition arrays of Os VII and Ir VIII were analyzed. All levels of these configurations in both spectra have been established. There are 77 lines in Os VII and 71 lines in Ir VIII classified. The parametric least squares fitting calculations are used to interpret both spectra. The 6s2S1/2-6p2P1/2,3/2 transitions in Ir IX have also been identified.
