摘要:

计算了核子共振区光子核反应的截面,以搜寻原子核中的共振-核子散射振幅。假设共振R在原子核内的基本光子-核子(γN)反应中产生并衰变,即γN→R→γN。共振在穿过原子核传播过程中与核子相互作用。因此,将计算得到的光子核反应截面与实验数据进行比较,以提取原子核中的共振-核子散射参数。

英文摘要:

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.
