181Hf(n,γ)182Hf反应截面测量(英文)
Measurement of Cross-Section for 181Hf(n,γ)182Hf Reaction
【摘要】 在中国原子能科学研究院重水研究堆上用活化法对反应堆中子引起的181Hf(n,γ)182Hf反应截面进行了测量.反应堆中样品照射位置的热中子与超热中子的通量比值约为10.照射后样品中的182Hf/180Hf和181Hf/ 180Hf的原子数比值是用热电离质谱测量的.本工作以180Hf(n,γ)181Hf反应截面(14.80±0.60b)为标准,测得的反应堆中子引起的181Hf(n,γ)182Hf反应截面值为80.0±5.6b.
【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)±(5.6b), given by 14.80±0.60b for the 180Hf(n,γ)181Hf reaction as a reference.
