Measurement of cross-sections for produced radionuclide in proton induced reactions on natHf up to 45 MeV

Abstract

We measured production cross-sections of Hf, Lu, and Ta radioisotopes from proton-induced reaction of natHf by using a stacked-foil activation and off-line γ-ray spectrometric technique at the MC-50 cyclotron of the Korea Institute of Radiological and Medical Sciences. The results were compared with the reported experimental data as well as the theoretical calculations based on the TALYS 1.4 code. The present results in the energy region from the threshold energy to 45MeV are in general good agreement with the other experimental data and calculated results. The present experimental results will play an important role in enrichment of the literature data base for proton-induced reactions on natural hafnium leading to various applications. Some of the investigated radionuclides (e.g. 177gLu) have remarkable applications in the field of nuclear medicine, a thin layer activation analysis, and a trace element analysis.
