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 4<i>d</i><sup>10</sup>–4<i>d</i><sup>9</sup>5<i>p</i> and 4<i>d</i><sup>10</sup>–4<i>d</i><sup>9</sup>4<i>f</i> were identified. In the AgI sequences, spectral lines arising from 5<i>s</i>–5<i>p</i>, 5<i>p</i>–5<i>d</i>, 4<i>f</i>–5<i>d</i>, and 4<i>f</i>–5<i>g</i> transitions were identified.
