论文摘要
计算核子共振区域中光核反应的横截面以搜索核中的共振核子散射幅度。假定共振$ r $是在基本光子 - 核子$（γn）$反应中产生和腐烂的，为$γn\ to r \至r \至γn$。共振与细胞核相互作用，同时通过细胞核传播。因此，将计算出的光核反应横截面与数据进行了比较，以提取细胞核中的共振核子散射参数。
The cross section of the photonuclear reaction in the nucleon-resonance region is calculated to search the resonance-nucleon scattering amplitude in the nucleus. It is assumed that the resonance $R$ is produced and decayed in the elementary photon-nucleon $(γN)$ reaction in the nucleus as $γN \to R \to γN$. The resonance interacts with the nucleons while propagating through the nucleus. Therefore, the calculated photonuclear reaction cross section is compared with the data to extract the resonance-nucleon scattering parameters in the nucleus.
