利用多色和能量选择性中子成像方法进行了中子透射测量与板的不同重建的历史铜合金含有Cu-Sn，Cu-Pb和Cu-Zn。通过与表列截面值的比较，可以准确定量和无损地检索合金成分的重量分数。结果表明，大部分的调查组合物，而其余的差异暗示在材料的不均匀性的讨论，一个很好的协议。通过这项研究，为以非侵入性的方式定量确定未知历史青铜合金物品的成分铺平了道路。
Neutron transmission measurements using polychromatic and energy-selective neutron imaging methods were performed with plates of different reconstructed historic copper alloys containing Cu–Sn, Cu–Pb and Cu–Zn. Through comparison with tabulated cross-section values, the alloy component weight fraction could in an accurate quantitative and non-destructive way be retrieved. The results show a good agreement for most of the investigated compositions while the discussion about the remaining discrepancies hints at material inhomogeneities. With this study the way is paved to determine quantitatively in a non-invasive way the composition of unknown historical bronze alloy objects.
