摘要：
本文测量了光核反应$^{nat}$ Ni（$γ$，xn）$^{57}$ Ni和$^{nat}$ Ni（$γ$，xn）$^{56}$ Ni的总韧致辐射通量平均截面< $σ$（E $_{γmax}$）>，其终点能量E $_{γmax}$ = 35 ~ 35. 94兆电子伏。实验是用NSC KIPT电子直线加速器LUE-40的电子束，用激活和离线$γ$射线光谱技术进行的。通量平均横截面< $σ$（E $_{γmax}$）> $_{th}$的计算是使用通过TANTS 1.95代码计算的部分横截面值$σ$（E）和通过GEANT 4.9.2计算的韧致辐射$γ$ -通量进行的。实验结果与理论计算和文献数据进行了比较。所获得的< $σ$（E $_{γmax}$）>值扩展了先前已知的实验数据的能量范围。
英文摘要：
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.
