Well-established methods for the measurements, the stacked-foil activation technique and gamma-ray spectrometry, were used. Production cross sections of 166,169Yb and 165,166,167,168,170,173Tm were determined. This is the first measurement of the cross sections of 166,170Tm. The integral yield of the medical radionuclide 169Yb was derived from the measured excitation function.Elsevier2019-12engjournal articleAMhttp://hdl.handle.net/2115/82507https://doi.org/10.1016/j.apradiso.2019.1088740969-8043AA10874887Applied Radiation and Isotopes154108874https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/82507/2/ARI154_108874.pdfapplication/pdf436.86 KB2019-12
