New data on cross-sections of deuteron induced nuclear reactions on gold up to 50 MeV and comparison of production routes of medically relevant Au and Hg radioisotopes

摘要

Investigations of cross-sections of deuteron induced nuclear reactions on gold were extended up to 50 MeV by using the standard stacked foil irradiation technique and high resolution gamma-ray spectrometry. New cross-sections are reported for the ~(197)Au(d,xn) ~(197m,197g,195m,195g,193m,193g)Hg and ~(197)Au(d,x)~(198m,198g,196m,196g,195,194)Au nuclear reactions. The application for production of the medically relevant isotopes ~(198)Au and ~(195m,195g,197m,197g)Hg is discussed, including the comparison with other charged particle induced production routes. The possible use of the ~(197)Au(d,x)~(197m,197g,195m,193m)Hg and ~(196m,196g)Au reactions for monitoring deuteron beam parameters is also investigated.
