Abstract: The radionuclide <superscript>149</superscript> Tb (t <subscript>1/2</subscript>  = 4.1 h) is a potential theranostic isotope which can simultaneously be used for targeted-alpha-particle therapy and positron-emission tomography. Feasibility experiments were performed to test a near-symmetric heavy-ion reaction of <superscript>63</superscript> Cu bombardment on monoisotopic <superscript>89</superscript> Y. The indirect reaction was studied to avoid isomer production. Offline gamma spectroscopy was used to quantify thick-target physical yields and experimental results show modest agreement to the fusion-evaporation code PACE4. A near-symmetric fission yield was also observed.<br /> (Copyright © 2021 Elsevier Ltd. All rights reserved.)
