Abstract

The spectrum of barium was recorded in the 250–1240-Å region on a variety of spectrographs. The sources used were a conventional triggered spark and a laser-produced plasma. The spectrum of seven-times ionized barium was investigated. Eight of thirteen levels reported earlier were confirmed. In the present analysis we have established a total of 74 levels, 66 of them new, belonging to the 5s25p,5s24f,5p3,5s5p5d,5s26p,5s25f, and 5s5p6s configurations in the odd-parity system and to the 5s5p2,5s25d,5s5p4f, and 5s26s configurations in the even-parity system. We carried out least-squares fitted and Hartree–Fock calculations to interpret the spectrum satisfactorily. One hundred thirty-nine lines have been classified in this spectrum, of which one hundred thirty are newly classified lines.
