摘要：

The L X-ray emission probabilities of Pu-239 and Pu-240 have been determined within the framework of a PTB project on the assay of plutonium in environmental samples by means of alpha-particle and L X-ray spectrometry. Spectra were obtained with a Si(Li) spectrometer using electroplated, isotopically-pure sources of known activity. The L multiplets were fitted with a function that takes into account the natural width of the X-ray lines and their Lorentzian shape. Emission probabilities for more than 15 different L X-ray lines or groups were determined for both Pu-239 and Pu-240. The total L X-ray emission probabilities were found to be 0.0463 +/- 0.0005 for Pu-239 and 0.1032 +/- 0.0015 for Pu-240.
