Production of 149Tb, 152Tb, 155Tb and 161Tb from gadolinium using different light-particle beams

149Tb, 152Tb, 155Tb and 161Tb can cover all the modalities of diagnostic and therapeutic purposes of nuclear medicine. The production cross sections and yields of radiotheragnostics terbium from x+152,154,155,156,157,158,160Gd reactions in the energy range 0.001 to 200 MeV are evaluated using TALYS1.9. Some p,d,he3-induced reactions show high yields to produce 149Tb while several p,d,t-induced reactions show larger yields to produce 152Tb. For 155Tb productions, number of p,t-induced reactions have higher production yields. To produce 161Tb, one deuteron and one triton induced reaction show bigger production yields. These calculations are compared with EMPIRE 3.2.2 and TENDL-2017 data for prospective reactions.
