摘要：
We activated Dy-nat with a 45-MeV energetic proton beam and studied the production cross-sections of the Ho-162m(,)161(,)159, Dy-159(,)15(7,)155, and Tb-161(,)160(,)156(,)155. The activation was carried out using an external beam from the MC-50 Cyclotron at the Korea Institute of Radiological and Medical Sciences, Korea. The stacked-foil activation method and off-line gamma-ray spectrometry were used to measure the excitation functions of the Dy-nat(p,x) reactions. The thick target yields of the reaction products were also estimated. The excitation functions of the Dy-nat(p,x) reactions were theoretically calculated using TALYS 1.9 code. The measured results were compared with the literature data and the calculated values from the TENDL-2017 library and were found to be in close agreement for most of the reactions.
