| Popis: | The observation of current in the afterglow of the discharge in a pulsed hollow-cathode lamp illuminated by tunable lasers, combined with optogalvanic techniques, provides a simple and reliable tool for multi-step photoionization spectroscopy studies. A three-photon photoionization spectroscopy study was performed in a uranium hollow-cathode lamp, using this combination of techniques. Single-, double- and triple-frequency photoionization paths were identified for uranium, in the range between 5900 and 6060 A. |
