The 5s2 5p4–5s5p5 transitions of Cs IV, Ba v, and La VI were observed with a sliding spark discharge and a 10.7-m normal-incidence spectrograph. The region of observation was 539–1282 Å. The energy parameters derived from least-squares fits to the experimental levels are compared with Hartree–Fock (HF) calculations. The fitted/HF ratios for the 5s25p4 configurations of the ions Te I–La VI are compared with the fitted/HF ratios for the 4s24p4 configurations of the ions Se I–Mo Ix.
