Abstract
The observation of current in the afterglow of the discharge in a pulsed ho llow-cathode lamp illuminated by tunable lasers, combined with optogalvanic techniques, provides a simple and reliable tool for multi-step photoioniza tion spectroscopy studies. A three-photon photoionization spectroscopy stud y was performed in a uranium hollow-cathode lamp, using this combination of techniques. Single-, double- and triple-frequency photoionization paths we re identified for uranium, in the range between 5900 and 6060 Angstrom.
