我们在三味线性模型的基础上研究了核子的光生，特别关注了介子和核子的末态相互作用（FSI）的影响。我们发现，由于FSI，阈值能量附近的光产生横截面有所增强。当它们处于前向角时，FSI很好地再现了阈值附近的能量依赖性。后向角截面也是研究相互作用强度的一个很好的探针。
We investigate thephotoproduction off the nucleon with a particular interest in the effect of the final-state interaction (FSI) of themeson and nucleonbased on the three-flavor linearmodel. We find an enhancement in the cross section of thephotoproduction near the-threshold energy owing to theFSI. With themeson at forward angles, the energy dependence near thethreshold is well reproduced with theFSI. The cross section at backward angles can also be a good probe to investigate the strength of theinteraction.
