Actinides, detection of trace amounts /Laser resonance ionization mass spectrometry /Isotope analysis of plutonium AbstractLaser resonance ionization mass spectrometry has been investigated as a method for the detection of trace amounts of actinides. High sensitivity and selectivity can be achieved by three-step photoionization followed by time-of-flight mass analysis. The laser system for photoionization consists of three dye lasers which are pumped simultaneously by a copper vapor laser. For mass determination a time-of-flight spectrometer with a mass resolution of about 1500 is used. By ionization via autoionizing states an overall efficiency of 4 X 10"' was determined for 23 ®Pu yielding a detection limit of less than 10 7 atoms. Isotope ratio measurements have been performed with synthetic plutonium samples.
