【 摘 要 】

In the frame of a systematical study of light ion induced nuclear reactions on hafnium, activation cross sections for proton induced reactions were investigated. Excitation functions were measured in the 38-65 MeV energy range for the Hf-nat(p,xn)(180g)'Ta-177,Ta-176,Ta-175,Ta-173, nat(Hf(p,x))180m, ,179m,175,173,172,171(Hf,) 177(g),173,172,171,170,169(Lu and) Hf-nat(p,x)Yb-169 reactions by using the activation method, combining stacked foil irradiation and off line gamma ray spectroscopy. The experimental results are compared with earlier results in the overlapping energy range, and with the theoretical predictions of the ALICE IPPE and EMPIRE theoretical codes and of the TALYS code reported in the TENDL-2015 and TENDL-2017 libraries. The production routes of Lu-172 (and its parent Hf-172) and of Yb-169 are reviewed.
