Theranostic mercury part 2: Production of 197(m)Hg via the 197Au(d,2n) reaction

Lebeda, O.; Walther, M.; Preusche, S.; Pietzsch, H.-J.; Steinbach, J.


The access to no-carrier-added 197(m)Hg using proton irradiation of gold targets and subsequent product separation was recently reported. One of the limiting factors of the large-scale production of this theranostic radionuclide is rather low yield of the 197Au(p,n)197(m)Hg reaction. In contrast, significantly larger cross-sections have been reported for 197Au(d,2n) reaction. In spite of somewhat larger linear energy transfer of deuterons in gold, the latter reaction seems to result in larger achievable activity of 197(m)Hg. We have, therefore, explored its potential for the 197(m)Hg production in a pilot experiment.
