    Notizen: Summary The hyperfine spectrum of the iodineR(115)20-1 line, at 570 nm, was obtained by conventional saturated absorption spectroscopy. The differences of nuclear electric-quadrupole (Δe Qq) and spin-rotation (ΔC) constants between theB andX states were determined by a least-square fit to the experimental data. This line may provide a good frequency reference in coincidence with the1 S 0-1 P 1 resonant transition of magnesium, at 285 nm, when this one is investigated with frequency doubled lasers.

    Notizen: Summary The optogalvanic signal (OGS) induced in a uranium-neon hollow-cathode discharge was measured as a function of the laser power density for the 0→16900 cm−1 (591.5 nm) uranium transition. Theoretical relations derived by solving a two-level system rate equations showed the OGS dependence on the laser photon flux, for a modulated c.w. light and for stimulated transitions starting from the ground state. A fitting of the theoretical relations to the experimental measurements allowed the determination of the σ0 τ product, that is, the saturation parameter of the transition. The results showed good agreement between the σ0 τ values obtained by the optogalvanic and the usual optical absorption processes.
