产生热光中子的阈附近γ共振

Gamma Resonances near Threshold for the Production of Thermal Photoneutrons

Silviu Olariu, Agata Olariu

摘要:

我们已经确定了(γ,n)共振的位置和(γ,n)反应的积分截面的上限,使用逆过程(n,γ)的数据。借助于这些数据,我们估计了用γ射线束照射靶所能产生的低能中子数。在通过(γ,n)反应产生热中子的反应中,我们提到积分截面上限为2.4 b-eV的185 Re(γ,n)184 Re和积分截面上限为0.9 b-eV的178 Hf(γ,n)177 Hf。

英文摘要:

We have determined the positions of the (gamma,n) resonances and upper limits for the integrated cross sections for the (gamma,n) reactions, using data for the inverse process (n,gamma). With the aid of these data we have estimated the number of low-energy neutrons which can be generated by the irradiation of a target with a gamma-ray beam. Among the reactions producing thermal neutrons via (gamma,n) reaction we mention 185Re(gamma,n)184Re with an upper limit of the integrated cross section of 2.4 b-eV, and 178Hf(gamma,n)177Hf with an upper limit of the integrated cross section of 0.9 b-eV.
