In this paper, we present, for the first time, a quantitative analysis carried out using time-resolved prompt gamma activation analysis (T-PGAA), a recent technique currently under development at the ISIS Neutron and Muon Source in Oxfordshire. T-PGAA is a neutron technique based on the radiative capture reaction that allows simultaneous acquisition of the photon energy emitted by the object during irradiation and the time of flight of the neutron that starts the capture reaction. We discuss results from two Cu-based certified standards from MBH Analytical Ltd: a leaded bronze and a brass, in preparation for future applications such as archaeological copper alloys. Results show the validity of the quantitative analysis calculated through a new piece of data analysis software developed in-house for this technique through comparison with the certified values and XRF results.

铜基合金作为散裂中子源T-PGAA定量分析的基准

在本文中，我们首次提出了使用时间分辨瞬变伽马活化分析（T-PGAA）进行的定量分析，这是牛津ISIS中子和Muon光源目前正在开发的最新技术。T-PGAA是一种基于辐射俘获反应的中子技术，它可以同时获取对象在辐照期间以及开始俘获反应的中子飞行时间中所发射的光子能量。我们讨论了MBH Analytical Ltd的两种基于铜的认证标准的结果：铅青铜和黄铜，为考古铜合金等未来应用做准备。
