| Abstract | Abstract Abstract Abstract Abstract Laser-induced photoionization and fluorescence signals were simultaneously recorded in atomic uranium using a single Nd: YAG-pumped dye laser for two specific cases. The uranium atoms in the ground state were ionized by single-color, three-photon photoionization technique resulting in the photoionization signal. The fluorescence signal was simultaneously obtained from the first-excited state involved in the photoionization process. The photoionization and the fluorescence signals were also estimated theoretically for several values of the photoionization cross-section for the transition between the second-excited state and the autoionization state using density matrix formalism. From the comparison of theoretically calculated ratios of fluorescence signals in the two specific cases with the experimentally obtained values, the photoionization cross-section for the 33801.06- 50701.59 cm -1 transition was obtained. |
