摘要：
替代反应方法是复合核反应截面直接测量的一种替代方案。我们引入理论工具，用于从利用质子非弹性散射作为替代反应机制的实验中提取俘获截面。这使得约束复合核衰变模型成为可能，该模型通常是俘获截面计算中最大的不确定性来源。本信描述了用于从$^{90}$Zr$(p,p'γ)$替代测量中同时推断$^{89}$Y$(p,γ)$和$^{89}$Zr$(n,γ)$截面的理论进展。
英文摘要：
The surrogate reaction method is an alternative to direct measurements of compound nuclear reaction cross sections. We introduce theory tools for extracting capture cross sections from experiments that use proton inelastic scattering as a surrogate reaction mechanism. This makes it possible to constrain compound nucleus decay models which are typically the largest source of uncertainty in capture cross section calculations. This letter describes the theory developments that were used to simultaneously infer $^{89}$Y$(p,γ)$ and $^{89}$Zr$(n,γ)$ cross sections from $^{90}$Zr$(p,p'γ)$ surrogate measurements.
