C(γ,η)X Reactions and Properties of N*(1535) in Nuclei

  • The η photon production reaction on nuclei is studied by employing N*(1535) resonance model. The parameters of the model are extracted by using experimental data of N* decay channels and fitting γp→ηp reaction cross section. The result shows that the theoretical values are in good agreement with experimental data if MN*=1550MeV. The total cross section of the η photoproduction on 12C is calculated. We find that the width of N*(1535) in nuclei increases because of corrections of many-body effects, and the interaction between N* and nuclei has the feature of repulsion.

Abstract: The η photon production reaction on nuclei is studied by employing N*(1535) resonance model. The parameters of the model are extracted by using experimental data of N* decay channels and fitting γp→ηp reaction cross section. The result shows that the theoretical values are in good agreement with experimental data if MN*=1550MeV. The total cross section of the η photoproduction on 12C is calculated. We find that the width of N*(1535) in nuclei increases because of corrections of many-body effects, and the interaction between N* and nuclei has the feature of repulsion.
