摘要：
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.
