Paper Abstract

The multistep photoionization of uranium atoms implies choosing an irradiation scheme and this choice is only possible if the following spectroscopic parameters are known: oscillator strength, isotopic shift, hyperfine structure, lifetime, autoionization spectrum. In order to measure these parameters two kinds of experimental set-up are used: laser induced fluorescence and laser induced photoionization techniques. Since the oscillator strengths determine the laser fluences needed for an effective atomic photoionization, this parameter must be accurately measured and two different methods are used: the saturation method, and branching ratio plus lifetime.
