The optogalvanic signal (OGS) induced in a uranium-neon hollowcathode discharge was measured as a function of the laser power density for the 0--* 16900 cm -1 (591.5 rim) 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 z0 r product, that is, the saturation parameter of the transition. The results showed good agreement between the ~0 r values obtained by the optogalvanic and the usual optical absorption processes.PACS 32.90 -Other topics in atomic spectra and interactions of atoms with photons.
