Abstract

The spectrum of indium has been photographed in the region 270–2400 Å on 3 and 10.7 m normal-incidence spectrographs. The sources used were a sliding spark and a triggered vacuum spark operated at various conditions. On the basis of these observations all levels of the 4<i>d</i><sup>8</sup>5<i>s</i> configuration and the unknown levels in the 4<i>d</i><sup>8</sup>5<i>p</i> configuration in In v have been located. The designation of the levels 4<i>d</i><sup>8</sup>(<sup>3</sup><i>P</i>)5<i>p</i><sup>2</sup><i>P</i><sub>1/2</sub><sup>0</sup> and 4<i>d</i><sup>8</sup>(<sup>1</sup><i>D</i>)5<i>p</i><sup>2</sup><i>P</i><sub>1/2</sub><sup>0</sup> have been interchanged. The parametric level fitting calculations for the configurations and the intensity calculations for the 4<i>d</i><sup>8</sup>5<i>p</i>–4<i>d</i><sup>8</sup>5<i>s</i> transitions confirm the analysis. There are 275 additional lines now classified in this spectrum.
