Spectra of Cs, Ba, La, Ce, Pr, Nd, and Sm ions were obtained with a low-temperature triggered spark produced with a 14.2 µF capacitor charged to voltages of 3–15 KV. They were photographed with a 10.7 m grazing incidence spectrograph in the range of 60–600 Å. Resonance lines in the PdI isolectronic sequences 4d10–4d95p and 4d10–4d94f were identified. In the AgI sequences, spectral lines arising from 5s–5p, 5p–5d, 4f–5d, and 4f–5g transitions were identified.
