232Th(p,x)225Ac

Bibliography of experimental data

A total of 12 datasets were found in 11 publications. Data are shown in Fig. of "All data" up to 200MeV. The experimental data are shown in Fig. "Selected" in comparison with TENDL calculations. The selected data and their experimental uncertainties together with the Padé fit and the estimated uncertainty of the fit, including 4% systematic uncertainty are shown in Fig. "Recommended"

 

Yields were calculated from the recommended cross sections.
