论文摘要
Bremsstrahung flux-aver的跨式$ \ langle {σ（e _ {\ rm {\ rm {γmax}}）} \ rangle $用于photonuclear Reactions $ {^{^{65} \ rm {cu}}}（cu}}}（cu}}}（cu}}}（cu}}}） $ {^{63} \ rm {cu}}（γ，n）^{62} \ rm {cu} $，$ {^{63} \ rm {cu}}}}}}}}}（γ，2n） $ {^{63} \ rm {cu}}（γ，3n）^{60} \ rm {Cu} $已在Bremsstrahlung端点能量$ e _ _ {\ rm {\ rm {γmax}} $ = 35-94 mev中测量。 通过使用激活和离线$γ$ -RAY光谱技术，使用NSC KIPT线性加速器LUE-40的电子束进行实验。通量平均跨区域的计算$ \ langle {σ（e _ {\ rm {γmax}}）}} \ rangle _ {\ rm {th}} $是使用横截面$σ（e）$ = talys1.95代码的crossSection $σ（e）$ values进行的。 结果表明，反应的实验平均横截面$ {^{65} \ rm {cu}}}（γ，n） $ {^{63} \ rm {cu}}（γ，2n）^{61} \ rm {Cu} $系统地高于Talys1.95代码中的理论估计。获得的$ \ langle {σ（e _ {\ rm {γmax}}）}} \ rangle $补充了反应$（γ，n）$和$（γ，2n）$的不同实验室的数据。对于反应，$ {^{63} \ rm {cu}}（γ，3n）^{60} \ rm {cu} $，$ \ langle {σ（e _ {e _ {\ rm {γmax}}}} \ rangle $的值。
The bremsstrahlung flux-averaged cross-sections $\langle{σ(E_{\rm{γmax}})}\rangle$ for the photonuclear reactions ${^{65}\rm{Cu}}(γ,n)^{64}\rm{Cu}$, ${^{63}\rm{Cu}}(γ,n)^{62}\rm{Cu}$, ${^{63}\rm{Cu}}(γ,2n)^{61}\rm{Cu}$ and ${^{63}\rm{Cu}}(γ,3n)^{60}\rm{Cu}$ have been measured in the range of bremsstrahlung end-point energies $E_{\rm{γmax}}$ = 35-94 MeV. The experiments were performed with the electron beam from the NSC KIPT 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 $\langle{σ(E_{\rm{γmax}})}\rangle_{\rm{th}}$ was carried out using the cross-section $σ(E)$ values from the TALYS1.95 code with the default options. It is shown that the experimental average cross-sections for the reactions ${^{65}\rm{Cu}}(γ,n)^{64}\rm{Cu}$, ${^{63}\rm{Cu}}(γ,n)^{62}\rm{Cu}$, ${^{63}\rm{Cu}}(γ,2n)^{61}\rm{Cu}$ are systematically higher than the theoretical estimates in the TALYS1.95 code. The obtained $\langle{σ(E_{\rm{γmax}})}\rangle$ supplement the data of different laboratories for the case of reactions $(γ,n)$ and $(γ,2n)$. For the reaction ${^{63}\rm{Cu}}(γ,3n)^{60}\rm{Cu}$, the values of $\langle{σ(E_{\rm{γmax}})}\rangle$ were measured for the first time.
