Cu-based alloys as a benchmark for T-PGAA quantitative analysis at ISIS pulsed neutron and muon source

In this paper, we present the quantitative analysis carried out for the first-time using time-resolved prompt gamma activation analysis (T-PGAA), a recent technique currently under development at ISIS Neutron and Muon Source in Oxfordshire. T-PGAA is a neutron technique, based on the radiative capture reaction, that allows the 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 standard samples provided by the MBH Analytical LTD: a leaded bronze and a brass, to be preparatory for future applications such as archaeological ones. Results show the validity of the quantitative analysis calculated through the new data analysis software developed for this technique through the comparison with the certified values provided by the industry for the standard alloys
