The spectrum of cesium was recorded in the 300–1240-Å region on a 3-m normal-incidence spectrograph and in the 100–300-Å region on a 10.7-m grazing-incidence spectrograph. The earlier analysis of Cs viii by KaufmanSugar [J. Opt. Soc. Am. B 4, 1919 (1987)] was confirmed, except for the two levels 5s5d 1D2 and 4d95s24f 1P1, and all other, earlier level values were revised. In addition, 12 levels of the 5p4f, the missing levels in the earlier-analyzed 5p2 1S0 and 5s6s 1S0, and all levels of the 5s4f,5s5f and 11 of the 12 levels of the 5p5d configurations of the odd-parity configurations have been located. The Hartree–Fock calculations with relativistic corrections and least-squares-fitting calculations were carried out, which helped in the satisfactory interpretation of the spectrum. One hundred ten lines are now classified in this spectrum, of which eighty-six are newly classified lines.
