一些国际机构建议研究生产用于核医学的放射性同位素的新途径和新设施。Lu是一种多用途放射性同位素，用于癌症的治疗和诊断（治疗诊断学），在神经内分泌肿瘤中取得了良好的成功，目前正在研究将其应用于更广泛的肿瘤。在少数核反应堆中，钚主要由钚的中子俘获产生。然而，它可以在高强度加速器中子设施中生产。基于加速器的中子设施中的中子能量高于热反应堆中的中子能量，因此，必须获得eV和keV范围内<$Yb（n，γ）截面的实验数据，才能准确计算<$Yb的产生，<$Yb的β衰变为<$Lu。目前，还没有从热到3 keV的<$transYb（n，γ）截面的实验数据。此外，在分辨共振区（RRR）中没有数据。这篇文章展示了在CERN的n_TOF设施上进行的Yb捕获测量的第一个结果。
Several international agencies recommend the study of new routes and new facilities for producing radioisotopes with application to nuclear medicine. ¹⁷⁷Lu is a versatile radioisotope used for therapy and diagnosis (theranostics) of cancer with good success in neuroendocrine tumours that is being studied to be applied to a wider range of tumours. ¹⁷⁷Lu is produced in few nuclear reactors mainly by the neutron capture on ¹⁷⁶Lu. However, it could be produced at high-intensity celeratorbased neutron facilities. The energy of the neutrons in accelerator-based neutron facilities is higher than in thermal reactors.Thus, experimental data on the ¹⁷⁶Yb(n,γ) cross-section in the eV and keV region are mandatory to calculate accurately the production of ¹⁷⁷Yb, which beta decays to ¹⁷⁷Lu. At present, there are not experimental data available from thermal to 3 keV of the ¹⁷⁶Yb(n,γ) cross-section. In addition, there is no data in the resolved resonance region (RRR). This contribution shows the first results of the ¹⁷⁶Yb capture measurement performed at the n_TOF facility at CERN.
