论文摘要
对于光核反应$^{nat} $ ni($γ$,xn)$^{57} $ ni and $ ni and $ ni(nat} $ ni(ni mutoge),$ ni(NAT} $ ni($ ni ni($ ni ni in In)端点能量E $ _ {γmax} $ = 35 ... 94 MEV。通过使用激活和离线$γ$ -RAY光谱技术,使用NSC KIPT电子线性加速器LUE-40的光束进行实验。使用部分横截面值$σ$(e)进行计算,计算通量平均横截面<$σ$(e $ _ {u $ _ {γmax} $)> $ _ {th} $。将实验结果与文献的理论计算和数据进行了比较。获得的<$σ$(E $ _ {γmax} $)>值扩展了先前已知的实验数据的能量范围。
The total bremsstrahlung flux-averaged cross-sections <$σ$(E$_{γmax}$)> for the photonuclear reactions $^{nat}$Ni($γ$,xn)$^{57}$Ni and $^{nat}$Ni($γ$,xn)$^{56}$Ni have been measured in the range of end-point energies E$_{γmax}$ = 35...94 MeV. The experiments were performed with the beam from the NSC KIPT electron linear accelerator LUE-40 with the use of the activation and off-line $γ$-ray spectrometric technique. The calculation of the flux-average cross-sections <$σ$(E$_{γmax}$)>$_{th}$ was carried out using the partial cross-section values $σ$(E) computed with the TALYS1.95 code and bremsstrahlung $γ$-flux calculated by GEANT4.9.2. The experimental results are compared with theoretical calculations and data from the literature. The obtained <$σ$(E$_{γmax}$)> values expand the energy range of previously known experimental data.
