• Holmium and erbium target
• proton and deuteron irradiation
• Er-161,Er-160 radioisotopes
• Dy-157,Dy-159 radioisotopes

Experimental excitation functions for long-lived products in proton induced reactions were measured with the activation method in the 37-65 MeV energy range on natural holmium. Stacked foil irradiation technique and high resolution gamma spectrometry were used in order to measure cross-section data for the production of Er-161, Er-160 and (DY)-D-159.157. For comparison of the production routes of medically related Er-161 and Er-160 radioisotopes new experimental cross section data were deduced for the Er-162(p,x)Er-161,Er-160 and Er-162(dx)Er-161,Er-160 reactions by re-evaluating gamma-ray spectra from earlier measurements. No earlier data were found in the literature for these reactions. The experimental data are compared with results of TALYS theoretical code reported in TENDL-2015.
