First high resolution measurement of neutron capture resonances in ¹⁷⁶Yb at the n_TOF CERN facility

Several international agencies recommend the study of new routes and facilities for producing radioisotopes with application to nuclear medicine. 177 Lu is a versatile radioisotope used therapy diagnosis (theranostics) cancer good success in neuroendocrine tumours that being studied be applied wider range tumours. produced few reactors mainly by neutron capture on 176 Lu. However, it could at high-intensity celeratorbased facilities. The energy neutrons accelerator-based higher than thermal reactors.Thus, experimental data Yb(n,γ) cross-section eV keV region are mandatory calculate accurately production Yb, which beta decays At present, there not available from 3 cross-section. In addition, no resolved resonance (RRR). This contribution shows first results Yb measurement performed n_TOF facility CERN.
