Abstract

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 Pd i isolectronic sequences 4d 10–4d 95p and 4d 10–4d 94f were identified. In the Ag i sequences, spectral lines arising from 5s–5p, 5p–5d, 4f–5d, and 4f–5g transitions were identified.
