摘要：
Production cross sections of Nb and Ta isotopes in the proton-induced reactions on Zr-nat and Hf-nat, respectively, were measured up to 14 MeV using a stacked-foil technique. The observed nuclides in the Zr-nat (p,x) reactions were Nb-90g.91m.92m.95m.95g.96, Zr-95, and Y-87g.88. In the Hf-nat(p,x) reactions, Ta-175,Ta-176,Ta-177,Ta-178,Ta-179 and Hf-175 were observed. The obtained cross sections for each nuclide were compared with the previously reported data and with the theoretical cross sections calculated by the TALYS-1.4 code. Thick-target yields of the observed nuclides were deduced from the measured production cross sections. (C) 2014 Elsevier Ltd. All rights reserved.
