Abstract
About 480 Ba III lines have been identified in the 10 800-400 Å range. The spectrum was emitted from a sliding spark discharge. 53 even and 58 odd energy levels have been established, including all levels of the 5p 55g, and parts of the 6g and 6h configurations. The 4f orbits show the contraction characteristic of the rare earths. Configuration interaction giving rise to s-f and p-g transitions have been observed. The 2 P 3/2 series limit is determined to be 289 100 ± 20 cm-1.Keywords
