Activation cross-sections of proton induced reactions on natHf in the 38–65 MeV energy range: Production of 172Lu and of 169Yb

Abstract

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 nat nat Hf(p,x) 169 Yb 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 172 Lu (and its parent 172 Hf) and of 169 Yb are reviewed.

Investigation of the deuteron induced nuclear reaction cross sections on lutetium up to 50 MeV: review of production routes for 177Lu, 175Hf and 172Hf via charged particle activation

“…2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and 13 and the numerical values are collected in Tables 3, 4 and 5. For completeness we have included also the cross section data for production of 172 Hf, measured in present study and reported earlier in [2]. Although all activation products except 177 Lu are formed in reactions on both stable Lu isotopes, remarkable surplus of 175 Lu over 176 Lu (97.4/2.6) results in dominance of the reactions on 175 Lu and in presence of a single peak in the measured excitation functions.…”

“…We have compared the charged particle production routes for 172 Hf/ 172 Lu generator in our previous paper [2]. Here we reproduce the figure of production yields completed with Lu + d reaction.…”

“…Preliminary results were presented in the RANC-2016 conference [1]. The activation cross section data for production of 172 Hf on natural hafnium were published in our paper investigating production routes of the 172 Hf/ 172 Lu generator and 169 Yb [2].…”
