Abstract: The reactor neutron cross-section for 181Hf (n,γ) 182Hf reaction has been measured with the activation method at the heavy water research reactor of China Institute of Atomic Energy. Thermal ionization mass spectrometry was used to determine the 182Hf/180Hf and 181Hf/180Hf atom ratios of the irradiated sample. The reactor neutron cross-section for 181Hf (n,γ) 182Hf reaction is 80.0±5.6 b, given by 14.80±0.60 b for the 180Hf (n,γ) 181Hf reaction as a reference.
