| Abstract: | In-source resonance ionization spectroscopy of uranium has been carried out as preparation for the analysis of low contaminations of nuclear material in environmental samples via laser mass spectrometry. Using three-step resonance ionization spectroscopy, 86 levels of odd parity in the energy range from 37,200–38,650 cm???1 were studied, 51 of these levels were previously unknown. Suitable excitation schemes for analytic applications are discussed. |
