摘要：

Resonance ionization mass spectrometry (RIMS) holds the promise of rapid, isobar-free quantification of actinide isotope ratios in as-received materials (i.e. not chemically purified). Recent progress in achieving this potential using two Pu test materials is presented. RIMS measurements were conducted multiple times over a period of two months on two different Pu solutions deposited on metal surfaces. Measurements were bracketed with a Pu isotopic standard, and yielded absolute accuracies of the measured Pu-240/Pu-239 ratios of 0.7 and 0.58 %, with precisions (95 % confidence intervals) of 1.49 and 0.91 %. The minor isotope Pu-238 was also quantified despite the presence of a significant quantity of U-238 in the samples.
