Several international agencies recommend the study of new routes and newfacilities for producing radioisotopes with application to nuclearmedicine. Lu-177 is a versatile radioisotope used for therapy anddiagnosis (theranostics) of cancer with good success in neuroendocrinetumours that is being studied to be applied to a wider range of tumours.Lu-177 is produced in few nuclear reactors mainly by the neutron captureon Lu-176. However, it could be produced at high -intensityaccelerator-based neutron facilities. The energy of the neutrons inaccelerator-based neutron facilities is higher than in thermal reactors.Thus, experimental data on the Yb-176(n,(sic)) cross-section in the eVand keV region are mandatory to calculate accurately the production ofYb-177, which beta decays to 177Lu. At present, there are notexperimental data available from thermal to 3 keV of the Yb-176(n,(sic))cross-section. In addition, there is no data in the resolved resonanceregion (RRR). This contribution shows the first results of the Yb-176capture measurement performed at the n\_TOF facility at CERN.
