Abstract

Cross-sections for the proton induced reactions on natural molybdenum leading to (93m)Tc, (93m+g)Tc, (94)Tc, (94m)Tc, (95)Tc, (95m)Tc, (96m+g)Tc, (99m)Tc, (90)Mo, (93m)Mo, (99)Mo, (90m+g)Nb, (92m)Nb, (95)Nb and (89m+g)Zr were measured in the proton energy range 8.4-37.1MeV on the cyclotron U-120M at the Institute of Nuclear Physics AS CR. Special attention was paid to excitation functions and thick target yields for the formation of (95m)Tc, a suitable tracer for (99)Tc, of (96m+g)Tc, which was proposed as a proton beam monitor, and of (99m)Tc and (99)Mo, the most widespread radionuclide generator pair in nuclear medicine. If appropriate, obtained data are compared with the heretofore published cross-sections.
