论文摘要

我们使用微钙化法报告了242PU的103-KEV和159-KEV伽马射线签名的测量。这是对这些伽玛射线的第一个观察结果，在对未准备好样品的无损测量中，这代表了核材料会计的重要进步。测量活动还可以作为带有便携式微钙化伽马射线光谱仪的现场活动的首次演示。对于103击伽玛射线，我们报告了提高的质心能量和排放概率。

We report measurements of the 103-keV and 159-keV gamma ray signatures of 242Pu using microcalorimetry. This is the first observation of these gamma rays in a non-destructive measurement of an unprepared sample, and so represents an important advance in nuclear material accountancy. The measurement campaign also serves as the first demonstration of a field campaign with a portable microcalorimeter gamma-ray spectrometer. For the 103-keV gamma ray we report an improved centroid energy and emission probability.
